Preparation And Storage

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

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.

The HP-3E4 monoclonal antibody recognizes CD158a. CD158a is a 58 kDa membrane glycoprotein, member of the killer-inhibitory receptor (KIR). The KIR family consists of transmembrane glycoproteins of the Ig superfamily expressed on <1-8% of NK cells and a subset of T cells which are involved in recognition of MHC class I molecules on target cells and inhibit cytotoxicity. CD158a is an antigen which recognizes HLA-C molecules (-Cw*0401 and -Cw*1503). This antibody is suitable for staining acetone-fixed, frozen tissue sections. It was reported that this clone also crossreacted with NKAT8 (CD158i) transfected cells.

This antibody is routinely tested by flow cytometric analysis. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.

Format Details
Down Arrow Up Arrow
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.
