Application Abreviews Notes
IP Use at an assay dependent concentration. PubMed: 23341456
WB Use a concentration of 0.1 - 0.3 µg/ml.
Approx 85kDa band observed in Human skeletal muscle lysates (calculated MW of 61.6kDa according to NP_004272.2). The observed molecular weight corresponds to earlier findings in literature with different antibodies (Iwasaki et al, Cancer Res. 2007 Nov 1;67(21):10252-9. PMID: 17974966).


  • Function

    Inhibits the chaperone activity of HSP70/HSC70 by promoting substrate release. Has anti-apoptotic activity.
  • Involvement in disease

    Defects in BAG3 are the cause of myopathy myofibrillar BAG3-related (MFM-BAG3) [MIM:612954]. A neuromuscular disorder that results in early-onset, severe, progressive, diffuse muscle weakness associated with cardiomyopathy, severe respiratory insufficiency during adolescence, and a rigid spine in some patients. At ultrastructural level, muscle fibers display structural alterations consisting of replacement of the normal myofibrillar markings by small, dense granules, or larger hyaline masses, or amorphous material.
  • Sequence similarities

    Contains 1 BAG domain.
    Contains 2 WW domains.

Customer reviews and Q&As


Thank you for providing more information about your protocol. We would like to emphasize that this is a Fast-Track antibody and not fully characterized yet. Please take a look at the Terms and Conditions for Fast-Track products. We cannot guarantee that the antibody will work in any application other than ELISA against the immunizing peptide and therefore we are unable to offer a refund if the antibody does not work in your application. However, Fast-Track antibodies are offered at a reduced price Our preliminary results show an approx 80 kDa band in HeLa and 293 lysates at 1ug of primary on Western blot application. Please note that currently we cannot find an explanation in the literature for the band we observe given the predicted size of approx. 67Kda according to NP_004272. In order to be able to reduce the high background, we would suggest loading 20 or 30 ug protein per lane and/or dilute the antibody a bit further down (i.e. 1/500 or 1/1000). We would suggest perhaps submitting a review on-line. In return we will forward a USD15/EUR15/GBP10 Amazon gift voucher. We hope this will help.
