Background Information

1. What is Hsp70/HSP1A?

HSP1A is a member of the Hsp70 (heat shock protein 70) proteins that act as molecular chaperones ensuring correct protein folding and preventing protein aggregation. Hsp70 protein production is greatly induced by various stress stimuli, including high temperature and toxins. Its expression is often elevated in various cancers.

2. FAQs for Hsp70

a. I cannot detect Hsp70 by western blotting

HSP70s are typically expressed at low levels under normal physiological conditions but are dramatically up-regulated in response to cellular stress. Try to always include cell lysate from cells subjected to stress conditions as a positive control.

a. What loading control can I use for cellular stress experiments with Hsp70?

Choosing a loading control antibody is an important step in western blotting experimental setup. We highly recommend using more than one loading control while developing new cellular stress assays to ensure that a given treatment does not alter expression of house-keeping genes. Hsp70 has a molecular size of 70 kDa, so we recommend using GAPDH (36 kDa), actin (42 kDa), or tubulin (50-55 kDa).
