An Open Letter About GenKit

To explain GenKit without causing boredom is actually pretty simple: we’ve identified the presence of a short DNA sequence found only in the Y-chromosome (ie the male gene). By copying this genetic snapshot a few million times, Steep Hill scientists can determine whether a plant is male or female with 99.9% accuracy.

CBS News Reports: As it grows, marijuana business becomes more tech savvy

"As things have come above board and more financing has become available and companies become less threatened that they would be put out of business, they have been more willing to invest in technology that is making cannabis products safer and more effective," Donald P. Land, a University of California, Davis, professor who is the chief scientific consultant for the cannabis testing firm Steep Hill, told CBS News. Land's company has been at the forefront of providing testing on cannabis products, introducing a system back in 2008 that tested for pesticides, heavy metals and the level of active ingredients known as cannabinoids in pot. A few weeks ago, it rolled out a mobile testing lab called QuantaCann II that can tell the potency and moisture of the cannabis in minutes. Land said the testing - which he points out is far more advanced than for most herbal products - has been especially important in the medical marijuana field, where different types of cannabis are used to treat different maladies like pain, nausea and nausea. Some contain THC, or tetrahydrocannabinol, which is responsible for many of marijuana's psychoactive effects while other strains contain CBD, a nonpsychoactive that has been shown to benefit some children who suffer seizures, he said. "The main result of introducing testing to cannabis has been a legitimization of cannabis as a medicine," he said. "Prior to that time, nobody knew what they were purchasing or using," he said. "Since that time, it's widely recognized that there are many different types of cannabis that lead to very different medicinal effects. The differences can only be discovered by doing chemical or genetic testing." Until now, much of the testing has been targeted to dispensaries and retailers. But the company is starting to go after growers with GenKit. The system allows a grower to have a leaf tested to determine the sex of a plant, since most growers prefer female plants known as sensimilla because of their higher yields. "Every grower who starts from seeds has to throw away half of their plants, [those] that emerge from the seeds as male," he said. "If they even have one male plant that produces pollen, that pollen is spread by the wind and their entire crop will likely be pollinated and overall yields will be reduced by 25 or more percent." http://www.cbsnews.com/news/as-it-grows-marijuana-business-becoming-more-tech-savvy/

Steep Hill Helps UC Davis Researchers Investigate Patient Deaths Linked to Fungal Infection

When a California medical cannabis patient died of a mysterious fungal infection, researchers at UC Davis wanted to know if the pathogen existed in the herbal remedy. Due to the federal prohibition of cannabis, the state school could not investigate cannabis directly. With the goal of linking the fungal infection to pathogens found on existing cannabis, UC Davis Medical Center requested that Steep Hill Labs in Berkeley conduct the tests on their behalf.

Mycotoxins, Molds, & Medical Cannabis

Molds (fungus) are living organisms that are often involved with the decomposition of organic matter. During the lifespan of a mold, it produces chemicals, by-products, and metabolites (like the alcohol produced by yeast during beer fermentation), including mycotoxins. Mycotoxins are so-named because they have been shown to be highly toxic to humans, animals, and plants. Along with acute toxicity (an immediate illness), continuous exposure to a specific mycotoxin often results in an allergic reaction resulting from buildup over time, that has the potential to be lethal to some patients. Once a patient becomes sick with a mycotoxin-induced type of allergy, the patient can remain allergic, becoming progressively sicker with each new exposure. Testing for mycotoxins — and removing them from cannabis flowers — is critical.

Cannabis, Terpenes, and the Entourage Effect

Mankind has been infatuated with terpenes for literally thousands of years, enjoying the aromas and flavors in beer, candy, perfumes, fruits, incense, and much more. In addition to the smells and tastes, we have continuously benefited from the diverse array of the medicinal and nutritional aspects found in terpenes. Terpenes likely make up the single largest family of chemical compounds available, from across the planet, to herbalists and apothecaries alike for use in compounding remedies and medicine.

Steep Hill Genetics | Understanding Phenosight™

Steep Hill uses a unique combination of chemical and genetic tests to help identify qualities before you plant. Using our suite of analytics, we can help growers find top phenotypes. We sex test seedlings as early as the second leaf set to determine if it’s a male; we assess whether seedlings have any unique genetic markers and then use an HPLC to determine THC/CBD ratio. Once the flowers are developed we can test to determine optimum harvest time and then test matured flowers for potency once curing is complete.

Why Does Each Cannabis Lab Report Total THC Differently?

Decarboxylation is the process whereby the acid cannabinoids (such as THCA) produced by the plant are heated to "activate" them by converting to the neutrals (such as THC). In the process, each acid molecule loses CO2 (carbon dioxide) which leaves as a gas. In concentrates, one can often see the bubbles during this process. Since the acid molecules lose mass (CO2 has a molar mass of 44 D), the percent by weight of ∆9THC will always be lower than the percent by weight of THCA. For THCA--->THC, the conversion results in THC (MW = 314.4 g/mol) from THCA (MW = 358.4 g/mol) so the ratio is 0.88. But that's not all that happens. In addition to losing CO2 and forming THC, THCA also forms other byproducts. In most instances, a good estimate of the total conversion efficiency is about 75%, but this will depend somewhat on temperatures and times used to decarboxylate. What is "Total THC"? The term "Total THC" does not have a well-defined meaning. It is calculated in different ways, producing very different results.

Cannabis, Terpenes and the Entourage Effect

Any given terpene can be found to exist in an amazing variety of different plants. For instance, ß-Caryophyllene is found in black pepper, cloves, some cannabis sativa strains, rosemary and hops. Cannabinoids were originally believed to only exist in family Cannabaceae, but have since been found in other families of plants such as family Linaceae (Flax), and Asteraceae (Echinaceae and Helichrysum). About a dozen plants containing CBD have been identified. The variety of plants producing the CBG-A needed to produce other cannabinoids is unknown at this point, the search is just starting. Not surprisingly, the heated/vaporized smoke of cannabis contains up to 50% terpenes, with cannabinoids normally accounting for 10-20% and the other terpenes accounting for another 10-30%.

What is Residual Solvent Analysis?

In the manufacturing of cannabis concentrates and extracts, solvents (water, butane, carbon dioxide, ethanol, etc.) are used to extract the active ingredients from plant material to produce a resinous, sometimes glassy product. Steep Hill regularly tests solvent extractions for residual solvents, helping manufacturers ensure the quality of their product, and empowering consumers with greater awareness of the composition of the products they are consuming.

Cannabinol (CBN): A Sleeping Synergy

Many who have heard of the cannabinoid Cannabinol (CBN) have a negative impression of the compound, as it is typically believed to be a degraded compound that appears in old, poorly stored cannabis. However, this bleak perspective is not entirely accurate.

Microbial Contaminant Remediation, Molds and Fungi in Cannabis

As the cannabis industry emerges, many questions surrounding the safety and efficacy of cannabis remain unanswered. In contrast with almost all other industries in the United States, where products are grown for human consumption and/or medical use, the cannabis industry has virtually no guidelines, limitations, or quality assurance mechanisms in place to protect its employees and consumers, aside from those provided by third parties such as Steep Hill. As a result, the quality of cannabis can vary widely from season to season, farm to farm, between growers, collective dispensaries, and even day to day within the same collective. An industry wide lack of standardized practices and remediation strategies virtually ensures that this will continue. This writeup aims to help providers begin a path towards effective quality assurance over the medicinal products they provide to patients, and become leaders in the industry in the process.

THCV: The Sports Car of Cannabinoids

The cannabis plant makes most cannabinoids, like THC, CBD, and CBC, out of CBG-A. CBGV-A appears in the plant much more rarely, and forms similar cannabinoids, except they only have 3 carbon tails (c3), instead of the more common 5 carbon tail (c5). These 3 carbon tailed cannabinoids are referred to as ‘varins’, such that the c3 version of THC (THC-c5) is named Tetrahydrocannabivarin (THC-c3).
