Background Information
BAG3 (Bcl2-associated athanogene 3) belongs to the BAG protein family, the co-chaperone that binds to Hsc70/Hsp70 through the BAG domain and modulates their activity in polypeptide folding. BAG3 contains also a WW domain and a proline-rich (PXXP) repeat, that mediate binding to partners different from Hsp70. Through interacting with different molecular partner, BAG3 influences several cell processes, such as apoptosis, autophagy and cell motility. BAG3 protein has been reported to sustain cell survival, resistance to therapy, and/or motility and metastatization in several tumor types, thus being identified as a potential target for anticancer therapies. In addition, defects in BAG3 are the cause of some myopathy. BAG3 normally migrates around 74-80 kDa; a slightly different molecular weight or a doublet form can be observed in some cell types and/or following cell exposure to stressors. A synaptosome associated form of 40 kDa has recently been described.

Reviews
What customers say
Across 8 reviews, users consistently rate this BAG3 antibody highly (average ~4.6/5). Western blot is the most common application, with users reporting strong, specific single bands and no non-specific binding at dilutions ranging from 1:100 to 1:5000. Specificity was confirmed in knockout tissue. Immunofluorescence and IHC also yielded good results. Tested tissues include mouse heart, human microglia, cardiomyocytes, brain, lung, and kidney. One user called it "the best BAG3 antibody" for western blots, and another noted reliable performance in autophagy studies. Overall, reviewers highlight excellent specificity, sensitivity, and consistency across species and applications.
