SYNONYMS
Chaperone protein hchA, EcHsp31, Hsp31, hchA, yedU, yzzC, b1967, JW1950.
INTRODUCTION
Escherichia coli Hsp31 (HchA) is a homodimeric member of the ThiI/DJ-1/PfpI superfamily which combines molecular chaperone and aminopeptidase activities. HchA uses temperature-induced exposure of structured hydrophobic domains to capture and stabilize early unfolding protein intermediates under severe thermal stress.
DESCRIPTION
hchA produced in E.Coli is a single, non-glycosylated polypeptide chain containing 303 amino acids (1-283 a.a.) and having a molecular mass of 33.3kDa.
hchA is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
SOURCE
Escherichia Coli.PHYSICAL APPEARANCE
Sterile filtered colorless solution.FORMULATION
The hchA contains (1mg/ml) 20mM Tris-HCl buffer (pH8.0), 20% glycerol 0.1M NaCl and 1mM DTT.STABILITY
hchA E.Coli Recombinant although stable at 4°C for 1 week, should be stored below -18°C.
Please prevent freeze thaw cycles.

E.coli genomic library construct 求教
最近我在做一个E.coli genomic library construct，遇到一些问题，向论坛上的大侠请教。请帮忙看看问题出在哪里。万分感谢！ 我的方法流程如下： 1。用SDS和蛋白酶K提取E.coli genomic DNA (用的是E.coli的一个突变菌株) 2。insert: Sau3AI digest E.coli genomic DNA, partail digestion, to get 2kb-5kb, 这一步我摸过酶切时间梯度，用0.1unit Sau3AI
