The good part is that excessive lactose is not harmful to cell growth. In contrast, IPTG serves only as inducer and cannot be metabolized, so it is more stable. However, I found that excessive IPTG will be "toxic" to cells and the cells aggregate and finally will be lysed if incubated further.

There is no scientific evidence that BHT is harmful in the amounts used in packaged food. Indeed, in small amounts, it may have anticancer effects similar to those provided by naturally occurring antioxidants. But studies of larger doses have shown mixed results.

This, along with the widespread use of VG in food and medicine suggest it is safe for humans. However, as with PG, there are limited studies on VG being inhaled as opposed to ingestion. A 2008 study of the toxicity of inhaling aerosolized glycerol found minimal risks.

We have ensured that our products are safe since 1903, when we first began offering crayons. All Crayola and Silly Putty products have been evaluated by an independent toxicologist and found to contain no known toxic substances in sufficient quantities to be harmful to the human body, even if ingested or inhaled.

PBDEs are ubiquitous in the environment, and, according to the EPA, exposure may pose health risks. According to U.S. EPA's Integrated Risk Information System, evidence indicates that PBDEs may possess liver toxicity, thyroid toxicity, and neurodevelopmental toxicity.

BHT is not a listed carcinogen, but some data have shown that it does cause cancer in animals. Rats fed BHT have developed lung and liver tumors (EFSA 2012). BHT has also been shown to cause developmental effects and thyroid changes in animals, suggesting that it may be able to disrupt endocrine signaling (EFSA 2012).

Medium Chain Triglycerides In general, vape juice that uses MCT as a carrier is considered to be much safer than juices with VG or PG. Unlike the other two options, MCT does not release carcinogenic byproducts when heated. It is also deemed to improve the bioavailability of cannabinoids and terpenes.

The galactoside, IPTG is used as the inducer instead of a lactose molecule, because lactose can be degraded in the cell, while IPTG can not.

Adverse reactions associated with the use of DTP (diphtheria and tetanus toxoids and pertussis vaccine adsorbed usp) include local redness, warmth, edema, induration with or without tenderness, as well as urticaria and rash.

The NTP has not classified exposure to hair dyes as to its potential to cause cancer. However, it has classified some chemicals that are or were used in hair dyes as “reasonably anticipated to be human carcinogens.”

Bt is a bacterium that is not toxic to humans or other mammals but is toxic to certain insects when ingested. ... Over two decades of review, the EPA and numerous scientific bodies have consistently found that Bt and engineered Bt-crops are not harmful to humans.

Terminal deoxynucleotidyl transferase (TdT), also known as DNA nucleotidylexotransferase (DNTT) or terminal transferase, is a specialized DNA polymerase expressed in immature, pre-B, pre-T lymphoid cells, and acute lymphoblastic leukemia/lymphoma cells.

Iodopropynyl butylcarbamate (IPBC) is a water-based preservative which—get this—was used originally in the wood and paint industries. It's now also used in some cosmetics and personal care products. However, even the cosmetic industry admits that this ingredient is toxic, and restrictions have been placed on its use.

For screening the clones containing recombinant DNA, a chromogenic substrate known as X-gal is added to the agar plate. ... Isopropyl β-D-1-thiogalactopyranoside (IPTG) is used along with X-gal for blue-white screening. IPTG is a non-metabolizable analog of galactose that induces the expression of lacZ gene.
