Rabbit Anti-Human Hsp70 pAb

Rabbit Anti-Human HSPA4 polyclonal antibody. HSPA4, one class of stress proteins, is comprised of multiple members, all of which bind ATP in vitro, but are localized within different intracellular compartments. These include: a) the constitutive HSPA8 (or cognate) present within the cytosol/nucleus, b) the highly stress-inducible HSPA4 present within the cytosol/ nucleus/nucleolus, c) the constitutive glucose regulated 78 kDa (or BiP) protein present within the lumen of the endoplasmic reticulum, and d) the glucose regulated 75 kDa protein present within the mitochondria. HSPA4 is typically not expressed in the cell under normal growth conditions, but is expressed at high levels in the cell experiencing stress. Consequently, detection of HSPA4 using an antibody specific for the inducible form is useful in ascertaining whether a stress response has occurred in the cell. It should be noted, however, that there is a constitutive level of HSPA4 expression in some cell types such as primates, e.g. human and monkey. Nevertheless increased expression of HSPA4 is observed in such cells following stress.
