{"product_id":"nsj-r30432-100ug","title":"Calpain 1 Antibody, 100 ug","description":"\u003cp\u003eCalpain-1 catalytic subunit is a protein that in humans is encoded by the CAPN1 gene. Calpain is an intracellular protease that requires calcium for its catalytic activity. Two isozymes, CAPN1 (mu-calpain) and CAPN2 (m-calpain), with different calcium requirements, have been identified. Both are heterodimers composed of L (large, catalytic, 82 kD) and S (small, regulatory, 30 kD) subunits. The isozymes share an identical S subunit, with the differences arising from the L subunits. By quantitative RT-PCR, Ueyama et al.(1998) found that expression of Calpain1\/2 mRNA was significantly increased in muscle biopsy samples derived from 5 men with progressive muscular dystrophy (e.g., DMD; 310200) and 2 men and 3 women with amyotrophic lateral sclerosis(ALS; 105400) compared with controls. Using cDNA clones as probes, Ohno et al.(1989, 1990) assign CAPNL1 to chromosome 11.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"100 ug","offer_id":51550514217240,"sku":"R30432","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_b956f6f5-8212-4b1c-bbc5-d3909c8d9d1e.jpg?v=1768316006","url":"https:\/\/danabiosci.com\/products\/nsj-r30432-100ug","provider":"Dana Bioscience","version":"1.0","type":"link"}
