Human Capase-7 aa. 25-42
Western blot (Routinely Tested), Immunoprecipitation (Tested During Development)
35 kDa (pro caspase-7), 17 kDa (active capase-7)
0.5 mg/ml
Aqueous buffered solution containing ≤0.09% sodium azide.

Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. Store undiluted at 4°C.

Recommended Assay Procedures

This antibody is routinely tested by western blot analysis (0.5-1.0 µg/ml).  Other applications not routinely tested at BD Biosciences Pharmingen include immunoprecipitation (1-2 µg/1 x 10^6 cells). 293 embryonic kidney (ATCC CRL-1673) are recommended as a positive control. Jurkat T cell leukemia (ATCC TIB-152) and Daudi Burkitt lymphoma (ATCC CCL-213) cell lines may also be used for these applications.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.
  3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

Caspase-7 is a member of a family of cysteine proteases which play a critical role in the induction of apoptosis. Caspase-7 is structurally and functionally most similar to caspase-3. These proteases are expressed as proenzymes which are processed into large and small subunits that associate to form the active enzyme. Caspase-7 may also exist as alternative splice forms, i.e., Mch3α and Mch3β.  A novel interaction between Mch3α and the 17 kDa subunit of caspase-3 has been demonstrated in vitro, producing a heteromeric enzyme which is proteolytically active.  Active caspase-7 can move to the mitochondrial fraction of cells  undergoing Fas-mediated apoptosis, whereas active caspase-3 is primarily cytosolic.  Caspase-7 is activated by caspase-31 and by granzyme B.  Active caspase-7 can cleave the nuclear substrate PARP1 as well as the sterol regulatory element-binding protein 1 (SREBP-1).  Caspase-7 migrates at a molecular weight of 35 kDa in SDS/PAGE.  Clone B94-1 recognizes the 35 kDa and 17 kDa form human caspase-7.  The specificity of the antibody was verified by immunoprecipitation and western blot analysis of active, recombinant human caspase-7 and of endogenous caspase-7 in cell lysates. A synthetic peptide corresponding to amino acids 25-42 of human caspase-7 was used as immunogen.

Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
