Rat (QC Testing)
Armenian Hamster IgG2, λ1
Rat LECAM-1 human IgG1 fusion protein
Flow cytometry (Routinely Tested)
0.5 mg/ml
Aqueous buffered solution containing ≤0.09% sodium azide.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with biotin under optimum conditions, and unreacted biotin was removed.

Recommended Assay Procedures

For detection of L-selectin on peripheral blood leukocytes, use of EDTA as anti-coagulant is recommended; heparin should not be used.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. An isotype control should be used at the same concentration as the antibody of interest.
  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. 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

The HRL1 monoclonal antibody specifically binds to L-selectin (LECAM-1, CD62L), which is detected on a small percentage of thymocytes and on most neutrophils and peripheral lymphocytes. CD62L is a 62-kDa (on neutrophils) or 65-kDa (on lymphocytes) receptor, with lectin-like and epidermal growth factor-like domains, which binds to sialylated oligosaccharide determinants on high endothelial venules (HEV) in peripheral lymph nodes. This member of the selectin adhesion molecule family appears to be required for lymphocyte homing to peripheral lymph nodes and to contribute to neutrophil emigration at inflammatory sites. L-selectin is rapidly shed from lymphocytes and neutrophils upon cell activation. In the mouse, the level of CD62L expression distinguishes naive CD4+T cells from effector/memory T helper cells. HRL1 antibody inhibits the ligand-binding activity of Lselectin in in vitro assays and slows in vivo leukocyte rolling on microvascular endothelium.

Biotin is a ubiquitous co-factor (also known as Vitamin B7) that has many properties that make it extremely useful for molecular biology. Biotin has an extremely high affinity for the Avidin family of proteins (Kd = 10-15 M), making it the perfect tool to link two molecules. Biotin labeled antibodies can be combined with any number of Avidin-conjugated probes in order to customize an assay to a particular need. This is especially useful in the case of magnetic cell separation using streptavidin/magnetic bead conjugates, or in the case of flow cytometry using streptavidin/fluorophore conjugates.
