Urea Biological Buffer

Guanidine Thiocyanate is a chaotropic agent. As one of the strongest protein denaturants, it inactivates nucleases more than twice as fast as Guanidine Hydrochloride.

HEPES is a zwitterionic buffer used to maintain pH of media used in cell cultures.

MES Monohydrate is a zwitterionic buffer that is not absorbed through cell membranes and is virtually transparent in UV light.

MOPS is a zwitterionic buffer used as a running buffer for denaturing gel electrophoresis and as a buffering agent in many biological and biochemical applications.

Tris, commonly used as a buffer in biochemistry and molecular biology, stabilizes the pH of solutions in electrophoresis and other biological applications.

Tris Hydrochloride is a stabilizing buffer in biological applications such as electrochromatography, UV analysis and HPLC.

Guanidine Hydrochloride 6M solution can be used to denature proteins which become randomly coiled with no residual structure.

HEPES Sodium Salt is a zwitterionic salt which is used in the preparation of a HEPES buffer solution. Its pH range of 9.5-11.5 makes an ideal buffer for pH maintenance. HEPES Sodium Salt interferes with the Folin protein assay. The tendency of this buffer to form radicals makes it unsuitable for redox stud...

L-Cysteamine HCl, a.k.a. 2MEA, has been manufactured for use as a critical process chemical for downstream biological drug manufacturing. L-Cysteamine HCl has been manufactured and purified under strict ICH-Q7 guidelines for excipient materials and can be considered an excipient grade product.
