Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.

Protocols

Specificity / Sensitivity

Hop Antibody detects endogenous levels of total Hop protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to human Hop. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from HeLa, NIH/3T3 and COS cells using Hop Antibody.

Background

HOP, also known as stress-induced phospho protein 1 (STIP), is a co-chaperone to the major heat shock proteins, Hsp70 and Hsp90, and appears in early receptor complexes (1,2). Through mutual binding to both Hsp70 and Hsp90, Hop functions as an adaptor that can integrate Hsp70 and Hsp90 interactions (3,4). HOP is an abundant and highly conserved protein which is composed of three tetratricopeptide repeat (TPR) domains (TPR1, TPR2a and TPR2b) and two DP repeat domains (DP1 and DP2), whose function has not been fully resolved (5).
