Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Tris-based buffer,50% glycerol
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Synthesizing the recombinant Mouse Bag3 protein generally involves integrating the DNA fragment that encodes the Mouse Bag3 protein (2-577aa) into a plasmid, introducing the recombinant plasmid into e.coli cells, followed by the selection and culturing of positive e.coli cells, induction of protein expression, and subsequent cell lysis. A N-terminal 6xHis-SUMO tag is fused to the protein. The protein is purified through affinity purification, and SDS-PAGE analysis is conducted to confirm the presence of the protein and determine its purity. The protein's purity surpasses 90%.

Target Background

Co-chaperone for HSP70 and HSC70 chaperone proteins. Acts as a nucleotide-exchange factor (NEF) promoting the release of ADP from the HSP70 and HSC70 proteins thereby triggering client/substrate protein release. Nucleotide release is mediated via its binding to the nucleotide-binding domain (NBD) of HSPA8/HSC70 where as the substrate release is mediated via its binding to the substrate-binding domain (SBD) of HSPA8/HSC70. Has anti-apoptotic activity. Plays a role in the HSF1 nucleocytoplasmic transport.
Gene References into Functions
  1. expression of the co-chaperone BAG3 and other chaperone-assisted selective autophagy factors was analyzed in the cellular, zebrafish and ky/ky mouse models. PMID: 29914939
  2. It is a cochaperone that mediates autophagy. PMID: 29304346
  3. Thus, BAG3 is critical for the protein turnover of small HSPs via activation of autophagy in the heart. PMID: 29409895
  4. BAG3 plays a relevant role in regulating SNCA clearance via macroautophagy, and the heat shock protein 70-BAG3-sequestosome 1 complex may be involved in this process. PMID: 28941726
  5. BAG3 directly stabilizes hexokinase 2 mRNA and promotes aerobic glycolysis in pancreatic cancer cells. PMID: 29114069
  6. BAG3 expression is required for neuronal differentiation and migration. PMID: 28144784
  7. interaction between BAG3 and HSP70 is essential for BAG3 to stabilize small heat shock proteins and maintain cardiomyocyte protein homeostasis PMID: 28737513
  8. The spatial regulation of mTORC1 exerted by BAG3 apparently provides the basis for a simultaneous induction of autophagy and protein synthesis to maintain the proteome under mechanical strain. PMID: 27756573
  9. Genetic variation in BAG3 plays an important role in the prevention of ischemic tissue necrosis. PMID: 28442482
  10. The aim of this study was to investigate the possible hemodynamic effects of BAG3 performing both in vitro and in vivo experiments. PMID: 27763645
  11. Our findings that BAG3 is localized at the sarcolemma and t-tubules while modulating myocyte contraction and action potential duration through specific interaction with the beta1-adrenergic receptor and L-type Ca(2+) channel provide novel insight into the role of BAG3 in cardiomyopathies and increased arrhythmia risks in heart failure. PMID: 26796036
  12. molecular association of MyHC and BIS is necessary for MyHC stabilization in skeletal muscle. PMID: 27034027
  13. BAG3 promotes pancreatic ductal adenocarcinoma growth by activating stromal macrophages. PMID: 26522614
  14. Bis is upregulated in astrocytes after hypoxia-ischemia; hypoxia-ischemia induces progressive cell death in the hippocampi of bis-positive mice, while hippocampal neurons are less vulnerable to hypoxia-ischemia in mice that lack Bis. PMID: 22907804
  15. Deletion of the bis gene results in a marked increase in the production of corticosterone that is associated with thymic atrophy. PMID: 21540452
  16. BAG3 and Hsc70 interact with actin capping protein CapZ to maintain myofibrillar integrity under mechanical stress. PMID: 20884878
  17. Results indicate that Bis functions to mediate cellular regulation of the stem cell niche on the vascular compartment. PMID: 20024912
  18. BAG3 alters the interaction between HSP70 and IKKgamma, increasing availability of IKKgamma and protecting it from proteasome-dependent degradation; this, in turn, results in increased NF-kappaB activity and survival PMID: 20368414
  19. BAG3 is not required for muscle development, this co-chaperone appears to be critically important for maintenance of mature skeletal muscle. PMID: 16936253
  20. The absence of Bis has considerable influences on postnatal growth and survival, possibly due to a nutritional impairment. PMID: 18840758
