Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  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.
  4. Please refer to for technical protocols.

FK506, one of multiple potent compounds that block T cell proliferation, is used for immunosuppressive therapy.  Several FK506-binding proteins (FKBPs) have been identified in the search for intracellular targets for FK506.  These include FKBP12, FKBP13, FKBP51, and FKBP52.  The immunosuppressive effects of FK506 and FKBPs result from the inhibition of the calcineurin phosphatase, a well known component of the signaling cascade leading to IL-2 production.  FKBP65 is another member of the FKBP protein family and contains the characteristic peptidylprolyl cis-trans-isomerase activity.  FKBP65 has been reported to be expressed in the lung, testis, brain, heart, and spleen.  Although it has a predicted molecular weight of 65 kDa, FKBP65 has been observed to migrate ranging from 68-72 kDa in SDS electrophoresis gels, perhaps, due to glycosylation and/or phosphorylation.

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.
