Most of the antibodies against Hsp70 can bind to the different isoforms of hsp70. Can someone kindly refer an antibody binding specifically to hsp70 only? Thank you.
Try contacting StressMarq Biosciences ( http://www.stressmarq.com ). They are something of specialists and should be able to tell you which (if any) of their anti-Hsp70 Abs don't react with the isoforms.
This is an excellent HSP70/ HSP72 antibody that I use. This antibody specifically detects HSP70/ HSP72 (HSPA1A) instead of HSP73/ HSC70 (HSPA8) & GRP78/ BiP (HSPA5).
