Human recombinant TMX2 (from E. coli)

Supplier: ProSci Inc.

TMX2 is a single-pass type I membrane protein and contains 1 thioredoxin domain. Thioredoxin plays an important role in various cellular processes through redox regulation. The molecular cloning and characterisation of one member of the thioredoxin superfamily, designated as TMX2.The TMX2 cDNA consists of 1644 nucleotides and contains an open reading frame encoding a protein of 372 amino acids with a predicted molecular mass of 42.5 kDa and an isoelectric point of 8.94. The TMX2 protein may possess an N-terminal signal peptide, a potential transmembrane domain, an Myb DNA-binding domain repeat signature, a thioredoxin consensus pattern, an endoplasmic reticulum (ER) membrane retention signal (KKXX-like motif), and a dileucine motif in the tail.

HPLC columns, ZORBAX® Bonus-RP

HPLC columns, ZORBAX® Bonus-RP

Supplier: Agilent

The ZORBAX® Bonus-RP column has a polar amide group embedded in a long alkyl chain. This novel bonding reduces interactions between basic compounds and the silica support, improving peak shape for the most difficult basic compounds. Peak shape and column lifetime are further improved by triple endcapping. In addition, diisopropyl side groups provide steric protection against acid hydrolysis for good lifetime and low pH. The Bonus-RP column provides an alternate selectivity to C18 and C8 alkyl bonded phases.
