LAMA2 encodes laminin α-2, a key subunit of laminin-211/221 heterotrimers that organize basement membranes and couple extracellular matrix architecture to cell-surface receptors including integrins and dystroglycan. Through these interactions, laminin α-2 supports adhesion, migration, and survival signaling and contributes to tissue integrity in skeletal muscle, peripheral nerve, and other basal lamina–rich environments. LAMA2-dependent matrix assembly influences cytoskeletal organization and mechanotransduction pathways that regulate myofiber stability and Schwann cell function. Disruption of LAMA2 is strongly associated with merosin-deficient congenital muscular dystrophy and related neuromuscular phenotypes, making it a relevant target for studying ECM-driven disease mechanisms.
Laminin α-2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the LAMA2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within LAMA2. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt LAMA2 function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of LAMA2-disrupted clones.
