Description

Introduction to ITGA1 Antibody, HRP Conjugated

The ITGA1 antibody is a polyclonal or monoclonal immunoglobulin raised against the Integrin alpha 1 protein, a cell surface receptor critical for laminin and collagen binding. The HRP (Horseradish Peroxidase) conjugation enables enzymatic signal amplification, commonly used in ELISA (Enzyme-Linked Immunosorbent Assay) and immunoblotting to detect ITGA1 expression levels in tissues or cell lysates .

Target Background

Function
Integrin alpha-1/beta-1 is a receptor for laminin and collagen. It recognizes the proline-hydroxylated sequence G-F-P-G-E-R in collagen. This receptor plays a role in anchorage-dependent, negative regulation of EGF-stimulated cell growth.
