TCEP-HCl Unit:5g which shifts to red light

which shifts to red light in vivo at 37°C

Antibiotics are often used in clinical in vitro tests known as antimicrobial susceptibility tests or ASTs to determine their efficacy against certain bacterial species

No yellowing after long storage

It is commonly used in cell culture media and as an ampholytic separator to create a pH gradient in isoelectric focusing

TCEP-HCl Unit:5g which shifts to red lightTCEP (Tris (2 Carboxyethyl) phosphine Hydrochloride) is an odorless reducing agent suitable for protein applications and in the preparation for electrophoresis. TCEP is water soluble, is stable in a variety of solutions and is particularly useful in the labeling of cysteine residues with maleimides, preventing the cysteines from forming disulfide bonds.
