Laminins are secreted glycoproteins, and are an important structural component of the extracellular matrix. The family of laminins is comprised of multiple isoforms, each formed from the oligomerization of various alpha, beta, and gamma chains. Laminin isoforms are expressed in a tissue-specific pattern, and contain multiple domains, which may include laminin EGF-like domains; laminin G-domains; laminin IV type A domains; and a laminin N-terminal domain. Laminins are capable of self-assembly to form a structural scaffold; they also bind to cell-surface molecules such as dystroglycan and mediate attachment of these molecules to the extracellular matrix. Laminins may also participate in intracellular signaling processes by binding to various integrin receptors. They are involved in cell adhesion, migration, differentiation, neurite outgrowth, and metastasis.

As originally characterized, clone AL-4 reacts with EHS mouse laminin, A chain (laminin α1). The epitope is mapped to the carboxy terminal globular domain on the A chain. Recent work by Scheele, et al. (2006) has further demonstrated that clone AL-4, under reducing conditions, recognized both the 200 kDa β1/γ1 band and the 400 kDa α1 band of mouse EHS laminin. However the affinity for the 400 kDa band was very low. AL-4 also demonstrated strong binding the Laminin β1. By ELISA the epitope for the AL-4 seemed to be located on the Laminin β1 chain, however the clone also recognizes the laminin α1 chain in immunoblots, thus AL-4 seems to show mixed cross reactivity to laminins α1 and β1, with the β1 reactivity being more prominent.
