ZooMAb^® antibodies represent an entirely new generation of recombinant monoclonal antibodies. Each ZooMAb^® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb^® antibodies are reliably available and ready to ship when you need them.

Clone 1D3 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects Laminin-5. It targets an epitope within 24 amino acids from the C-terminal half.

KLH-conjugated linear peptide corresponding to 24 amino acids from the C-terminal half of human Laminin subunit 2 (Laminin-5).

Laminin subunit gamma-2 (UniProt: Q13753; also known as Cell-scattering factor 140 kDa subunit, CSF 140 kDa subunit, Epiligrin subunit gamma, Kalinin subunit gamma, Kalinin/nicein/epiligrin 100 kDa subunit, Ladsin 140 kDa subunit, Laminin B2t chain, Laminin-5 subunit gamma, Large adhesive scatter factor 140 kDa subunit, Nicein subunit gamma) is encoded by the LAMC2 (also known as LAMB2T, LAMNB2) gene (Gene ID: 3918) in human. Laminin is a major basement membrane glycoprotein consisting of α, β, and γ chains that are bound to each other by disulfide bonds.  It is a key component of the anchoring complex connecting keratinocytes to the underlying dermis. Over 15 different isoforms have been reported in the laminin family that are expressed in a tissue-specific manner and play different role in each tissue. γ2, a subunit of Laminin-5 (also known as Laminin-332), is synthesized with a signal peptide (aa 1-21), which is subsequently cleaved off to generate the mature form. It is reported to be frequently over-expressed as a monomer or as the β3-γ2 heterodimer in invasive cancers and is regarded as an invasion marker. It has 8 EGF-like domains. The cell adhesion and motility activities of Laminin-5 are reported to be regulated by the proteolytic cleavage of the short arm of Laminin 2 chain by BMP-1 or MT1-MMP. This cleavage releases a 45 kDa N-terminal proteolytic fragment (γ2pf). The short arm and γ2pf can be further cleaved by serine proteases and by matrix metalloproteinases resulting in the release of small N-terminal fragments. γ2pf‐like fragments have been reported to be present in conditioned media of cultured cancer cells and in sera from human cancer subjects. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
