Immunoprecipitation: Hsp70 / Hsc70 Antibody (13D3) [NB120-2788] - Analysis of HSC70 was performed on HeLa cells. Antigen-antibody complexes were formed by incubating 500ug whole cell lysate with 2ul of HSC70 monoclonal antibody overnight on a rocking platform at 4C. The immune complexes were captured on 50ul Protein A/G Plus Agarose, washed extensively, and eluted with Lane Marker Reducing Sample Buffer. Samples were resolved on a 4-20% Tris-HCl polyacrylamide gel, transferred to a PVDF membrane, and blocked with 5% BSA/TBST for at least 1 hour. The membrane was probed with a HSC70 monoclonal antibody at a dilution of 1:1000 overnight rotating at 4C, washed in TBST, and probed with goat anti-mouse IgM-HRP secondary antibody for at least 1 hour. Chemiluminescent detection was performed using SuperSignal West Dura.

  • Immunoblotting
  • Immunocytochemistry/Immunofluorescence 1:20 - 1:200
  • Immunohistochemistry 1:20 - 1:200

  • Immunoprecipitation 2 ul
  • Western Blot 1:1000 - 1:5000
• Application Notes: WB: Detects an approx. 70 kDa protein representing Hsc 70. By 2D gel electrophoresis, this antibody binds strongly to Hsc 70 and faintly to HSP 70 both before and after heat shock. IHC: Staining of Hsc 70 in mouse spermatids/spermatozoa results in staining restricted to the post acrosomal region in condensing spermatids and to the midpiece in spermatozoa. May be useful in IHC-Fr. Use in Immunoblotting reported in scientific literature (PMID 28095639).
• Theoretical MW: 70 kDa.
  Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Background

Heat shock proteins (HSP's) or stress response proteins (SRP's) are synthesized in variety of environmental and pathophysiological stressful conditions. Many HSP's are involved in processes such as protein denaturation-renaturation, folding-unfolding, transport-translocation, activation-inactivation, and secretion. HSP70 is found to be associated with steroid receptors,actin, p53, polyoma T antigen, nucleotides, and other unknown proteins. Also, HSP70 has been shown to be involved in protective roles against thermal stress, cytotoxic drugs, and other damaging conditions.
