General description
Laminin subunit alpha-2 (UniProt: P24043; also known as Laminin M chain, Laminin-12 subunit alpha, Laminin-2 subunit alpha, Laminin-4 subunit alpha, Merosin heavy chain) is encoded by the LAMA2 (also known as LAMM) gene (Gene ID: 3908) in human. Laminins are a family of heterotrimeric extracellular glycoproteins consisting of α, β, and γ chains that are bound to each other by disulfide bonds into a cross-shaped molecule comprising one LONG® and three short arms with globules at each end. Thus far five α, three β, and three γ subunits are known, which assemble into at least 15 different laminin molecules. Laminin α2 is a glycoprotein with multiple EGF-like domains and is synthesized with a signal peptide (aa 1-22), which is subsequently cleaved off. It is expressed in multiple tissues, including placenta, striated muscle, cardiac muscle, pancreas, lung, spleen, skin, bone, and some regions of the brain. Laminin α2 binds to cells via a high Affinity™ receptor and mediates the attachment, migration, and organization of cells into tissues during embryonic development by interacting with other extracellular matrix components. Mutations in LAMA2 gene have been linked to Merosin-deficient congenital muscular dystrophy 1A (MDC1A) and limb-girdle muscular dystrophy that results in muscle weakness and atrophy. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, Affinity™, reproducibility, and stability over conventional monoclonals.

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.
Immunogen
80 kDa fragment from the C-terminal region of human Laminin 2.
Application
Quality Control Testing
Evaluated by Western Blotting in Human heart tissue lysate.
Western Blotting Analysis: A 1:10,000 dilution of this antibody detected Laminin 2 in Human Heart tissue lysate.
Tested Applications
Immunohistochemistry (Paraffin) Analysis: A 1:1,000 dilution from a representative lot detected Laminin 2 in human heart and human cerebral cortex tissue sections.
Immunofluorescence Analysis: A 1:1,000 dilution from a representative lot detected Laminin 2 in human cerebral cortex tissue sections.
Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user
Biochem/physiol Actions
Clone 5H2 is a ZooMAb® mouse recombinant monoclonal antibody that specifically detects Laminin 2. It targets an epitope within the C-terminal region.
Physical form
Purified recombinant mouse 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.
Preparation Note
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.
Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
Other Notes
Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
