Liquid, containing 20mM Tris-HCl, pH 7.5, 0.15M NaCl, 1mM EDTA.

~34kDa

≥95% (Western blot analysis)

Produced in E. coli.

PLEASE NOTE: Tetra-ubiquitin may undergo complex formation to give higher molecular weight multimers upon heating and, consequently, the duration of any heating steps during use should be minimised. The exact nature of the multimeric complexes is not known at this time.
