Product Details
Down Arrow Up Arrow

BD Pharmingen™
Mouse (QC Testing)
Armenian Hamster IgG3, κ
gp49B-Fc fusion protein composed of extracelluar domain of gp49B
Flow cytometry (Routinely Tested), ELISA, Immunoprecipitation, Induction (Reported)
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

For optimal staining, we recommend the use of biotinylated anti-hamster IgG mAb G192-1 (Cat. no. 554025) as the second-step antibody, followed by a bright third-step reagent such as Streptavidin-APC (Cat. no. 554067) or Streptavidin-PE (Cat. no. 554061).

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.
  3. Although hamster immunoglobulin isotypes have not been well defined, BD Biosciences Pharmingen has grouped Armenian and Syrian hamster IgG monoclonal antibodies according to their reactivity with a panel of mouse anti-hamster IgG mAbs. A table of the hamster IgG groups, Reactivity of Mouse Anti-Hamster Ig mAbs, may be viewed at
  4. 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 H1.1 monoclonal antibody specifically reacts with gp49B, a structural homolog of the human Killer Inhibitory Receptors (KIR), and with the truncated related molecule gp49A.  The gp49 receptors are expressed on myeloid cells of adult bone marrow, spleen, and liver and fetal liver.  They are not found on resting lymphoid cells, but their expression is upregulated on activated NK cells.  gp49B is a member of the Ig superfamily containing two cytoplasmic ITIM (Immunoreceptor Tyrosine-based Inhibitory Motif) domains, while gp49A has no ITIM.  Although its ligand is unknown, it is established that cross-linking of gp49B can suppress cell activation events.

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.
