There are a number of ELISA Kits available for the measurement of hsp70A1, another term for the human protein, heat shock protein family A (Hsp70) member 1A. Other synonyms may include: heat shock 70 kDa protein 1A, HSP70-1/HSP70-2, HSP70.1/HSP70.2, Heat shock 70 kDa protein 2, epididymis secretory protein Li 103, heat shock 70kD protein 1A, and heat shock 70kDa protein 1A. It is encoded by the HSPA1A gene to yield a protein 641 amino acids in length and 70.1 kDa in size. However, there are up to 2 reported isoforms. The protein is categorized into the Heat shock protein 70 family. Versions of hsp70A1 are present in other organisms, including: Mouse, Rat, Zebrafish, Frog.
