General description

Purified mouse monoclonal antibody generated by immunizing RBF/Dn mice with the specified immunogen and fusing splenocytes with NS-1/FOX-NY mouse myeloma cells (see application references). Recognizes the α3 integrin subunit.

Recognizes the α3-subunit of the α31 integrin complex protein in human mononuclear cells.

This Anti-Integrin α₃ Mouse mAb (P1B5) is validated for use in Cell Inhibition Assays, FC, IF, IP for the detection of Integrin α₃.

Cell Inhibition Assays (1-5 µg/ml, see application references)

Flow Cytometry (1-5 µg/ml)

Immunoblotting (not recommended)

Immunofluorescence (1-5 µg/ml)

Immunoprecipitation (1-2 µg/sample)

Paraffin Sections (not recommended)

Physical form

Lyophilized from a volatile buffer, 100 µg BSA.


We recommend resuspending the lyophilized antibody with sterile PBS, pH 7.4, or sterile 20 mM Tris-saline (20 mM Tris containing 0.15 M NaCl), pH 7.4, to yield a final concentration of 100 µg/ml; product will be more stable if 0.1% sodium azide is included (do not add azide if antibody is to be used with viable cells). Lyophilized antibody should be resuspended at 4°C with occasional gentle mixing for at least 2 h. Following reconstitution, refrigerate (4°C) for short-term storage (with azide) or aliquot and freeze (-20°C) for short-term storage.
