Description: Trichloroacetic acid is an acetic acid analogue commonly used to precipitate proteins, DNA and RNA. In the presence of SDS Trichloroacetic acid will precipitate proteins which can then be quantified by the Lowry method. The compound has also found uses as a decalcifier and fixative in microscopy, in protein sequencing, detecting albumin and organic synthesis.
Trichloroacetic acid is used in protein precipitation; has been used to determine protein concentration by quantitative precipitation. It is also used as a decalcifier and fixative in microscopy. A protocol for the precipitation of nucleic acids can be found in Molecular Cloning. Rats exposed to chronic sublethal amounts of trichloroacetic acid displayed an increase in serum bilirubin with a decrease in hematological proteins and cholesterols along with significant decreases in red blood corpuscles, mean cell volume, mean corpuscular hemoglobin, hemoglobin and hematocrit. In mice the production of liver tumors was associated to Trichloroacetic acid, which is also a known mouse hepatocarinogen. On the guinea pig trichloroacetic acid was observed to be a mild alergen on the skin.

Description: Choline chloride is an organic compound and a quaternary ammonium salt. It is a weak acid. Choline chloride is the salt of the naturally occurring choline, the pre-stage of the neurotransmitter acetylcholine, which is important for mnemonic and thought-processes. Choline occurs naturally in fungi, hop and kingcups and as integral part of lecithin. Choline chloride is a common food additive in animal husbandry
The enzymatic activities of butyrylcholinesterase (BChE) and paraoxonase 1 (PON1), two serum enzymes synthesized by the liver and related with inflammation, were decreased in a sepsis animal model injected with LPS. Choline chloride administered intravenously at 20 mg/kg body weight prevents the LPS-mediated decreases in the activities of these two enzymes.
Choline chloride is used as a source of methyl groups for methyl-transfer reactions.

Description: Sodium azide used as a preservative for laboratory reagents; a bacteriostatic agent in storage solutions. Inhibits gram negative flora so is therefore included in culture media for the selective isolation of Streptococci and Staphylococci. It has been used to avoid bacterial contamination during RPC-5 column chromatography of DNA fragments.
Catalyst for:
• Oxidative decarboxylation
• Michael addition reactions
Reagent for synthesis of
• Blue fluorescent copolymers
• Metal phosphonates
• Arenes via aminations
Involved in regioselective synthesis of prianosin B
It is also a useful probe reagent, mutagen, and preservative. In hospitals and laboratories, it is a biocide (A biocide is a chemical substance or microorganism which can deter, render harmless, or exert a controlling effect on any harmful organism by chemical or biological means.)
Sodium Azide is an inhibitor of peroxidase, myeloperoxidase, superoxide dismutase, galactose oxidase, catalase, haemoprotein enzymes and O2 evolution in photosynthesis. The mechanism of its inhibition and toxicity may be due to metal ion complexation and displacement from enzyme.

Description: Glutaraldehyde is a bifunctional protein cross-linking reagent, reacting with NH2 groups to form Schiff's bases.
Sporicidal agent. Glutaraldehyde reacts through cross-linking to impart water resistance to protein and polyhydroxy compounds. It is also a reducing agent for photochemicals. In organic syntheses, the reactive carbonyl groups of glutaraldehyde suggest its use as an intermediate for the production of resins, dyestuffs, and pharmaceuticals. Glutaraldehyde is a disinfectant, which is rapidly effective against vegetative forms of Gram-positive and Gram-negative bacteria. It is also effective against acid-fast bacteria, bacterial spores, some fungi and viruses, including hepatitis B virus and human immunodeficiency virus. It can also be used for stabilization of proteins on agarose beads, activation of polystyrene and glass for immobilization of antibodies and antigens, and coupling peptides onto carrier proteins. Can be used for preparing emulsions for making photographic film. Also for use as an electron microscopy fixative or cell fixation.

Description: Polyethylene glycol (PEG) is a condensation polymer of ethylene oxide and water. PEGs are susceptible to oxidative degradation in the presence of air. Minimizing the exposure of PEG to elevated temperatures and/or exposure to oxygen, or addition of an antioxidant can limit the amount of degradation. PEGs do not hydrolyze or deteriorate upon storage. PEGs do not support the growth of molds. PEG is incompatible with phenol and may reduce the antimicrobial action of other preservatives.
