There are a number of ELISA Kits available for the measurement of Heat Shock Protein 1B, another term for the human protein, heat shock protein family A (Hsp70) member 1B. Other synonyms may include: heat shock 70 kDa protein 1B, HSP70-1/HSP70-2, HSP70.1/HSP70.2, Heat shock 70 kDa protein 1, heat shock 70 kDa protein 1A/1B, heat shock 70kD protein 1B, and heat shock 70kDa protein 1B. It is encoded by the HSPA1B gene to yield a protein 641 amino acids in length and 70.1 kDa in size. Versions of Heat Shock Protein 1B are present in other organisms, including: Mouse, Rat, Frog.
