Scientific Background
Laminins, a family of extracellular matrix glycoproteins, are the major noncollagenous constituent of basement membranes. They have been implicated in a wide variety of biological processes including cell adhesion, differentiation, migration, signaling, neurite outgrowth and metastasis. Laminins are composed of 3 non identical chains: laminin alpha, beta and gamma (formerly A, B1, and B2, respectively) and they form a cruciform structure consisting of 3 short arms, each formed by a different chain, and a long arm composed of all 3 chains. Each laminin chain is a multidomain protein encoded by a distinct gene. Several isoforms of each chain have been described.

Safety & Handling
Research use only
This protein was produced in Mammalian (HEK293). Mammalian expression enables human-like glycosylation, correct disulfide bond formation, and proper protein folding — all critical for proteins used in binding interaction studies (SPR/BLI) and antibody characterisation. For transmembrane proteins expressed as ectodomains or nanodisc preparations, the expression system directly affects binding conformation and assay performance.
The molecular characterisation of this construct is: LAMA4(Ala25-Ala1823) 6×His tag. Cross-reference with the UniProt entry (Q16363) to confirm the expressed region includes your domain of interest — receptor-binding domain, extracellular domain, or specific epitope — before ordering.
The purity of the protein is greater than 85% as determined by SDS-PAGE and Coomassie blue staining.. A gel image showing the protein band is provided with each lot on the Certificate of Analysis. This high-purity specification is suitable for SPR/BLI kinetics measurements, ELISA standard curve development, and antibody epitope binding studies.
Please refer to the Certificate of Analysis (CoA) for reconstitution instructions for your specific lot. Storage: Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (A Prepare single-use working aliquots after reconstitution to avoid repeated freeze-thaw cycles. Lyophilized protein is stable for 12 months at −80°C from the date of receipt.
