Anti-LAMB3 Antibody

The Anti-LAMB3 Antibody from Antibodies.com is a rabbit polyclonal primary antibody that targets laminin subunit beta-3 (LAMB3), a critical component of laminin-332 in epithelial basement membranes. This unconjugated IgG reagent is validated for immunohistochemistry (IHC) on human tissue sections, supporting research into epidermal adhesion, basement membrane biology, and wound healing. Investigators studying junctional epidermolysis bullosa, squamous cell carcinoma invasion, and keratinocyte differentiation routinely apply LAMB3 immunostaining to map protein distribution across the dermal-epidermal junction and tumor margins. The antibody is supplied as 100 µl of liquid intended for use with standard chromogenic or fluorescent IHC workflows. For optimal stability, refrigerate the vial at typical short-term antibody storage temperatures and aliquot upon receipt if extended use is planned; protect from light and limit freeze-thaw cycles to preserve binding activity.
