Mouse anti Human laminin alpha 2 antibody, clone 5H2 recognizes the ~80 kDa fragment of laminin subunit alpha-2, also known as the laminin M chain, laminin-12 subunit alpha, laminin-2 subunit alpha, laminin-4 subunit alpha or merosin heavy chain. Laminins are trimeric basement glycoproteins consisting of three non-identical multi-domain chains (alpha, beta and gamma) each encoded by a distinct gene. The alpha-2 chain is a subunit of Laminin-2 and Laminin-4, widely expressed in the basement membrane of skeletal muscle and peripheral nerves. Laminins are thought to mediate cell attachment, migration, proliferation and differentiation with other extracellular matrix components.

Mutation of the LAMA2 gene can lead to the development of Merosin-deficient congenital muscular dystrophy 1A (MDC1A), a condition characterized by hypotonia, proximal weakness, hyporeflexia and difficulty walking (Tazek et al. 2003).

Storage Information

This product is shipped at ambient temperature. It is recommended to aliquot and store at -20°C on receipt. When thawed, aliquot the sample as needed. Keep aliquots at 2-8°C for short term use (up to 4 weeks) and store the remaining aliquots at -20°C.

Avoid repeated freezing and thawing as this may denature the antibody. Storage in frost-free freezers is not recommended.
