Application
层粘连蛋白支持多种细胞类型的生长和分化，包括表皮、内皮、神经、肌肉和肝脏细胞。 建议将其按1-2 μg/cm2用作细胞培养的基质。 最佳的浓度的确取决于细胞类型以及应用或研究目标。
Biochem/physiol Actions
层粘连蛋白是动物组织中结构性支架的组成部分。 它们通过内功素和基底膜聚糖与IV型胶原结合，并通过整合素受体、dystroglycan糖蛋白复合物以及Lutheran血型糖蛋白与细胞膜结合。 层粘连蛋白具有胶原结合、细胞粘附、肝素结合和神经突向外生长片段的活性结构域。
Preparation Note
该产品是在含有150 mM NaCl的50 mM Tris-HCl中以0.5 mg/mL的浓度提供。 它被0.2μm过滤。在使用前在2-8°C将该溶液缓慢解冻以避免形成凝胶。 作为一种涂层溶液，在灭菌平衡盐溶液中稀释，涂层结构表面有最小体积，在37℃培育2小时。 在细胞铺板之前用PBS洗涤3次。层粘连蛋白可储存在2-8°C达一个月。
Other Notes
层粘连蛋白是一种细胞外基质多结构域三聚体糖蛋白，并且是支持粘附、增殖和分化的基底膜的主要非胶原组分。 层粘连蛋白是由通过多个二硫键连接的A、B1和B2链组成。使用胃蛋白酶处理和免疫亲和层析，层连蛋白产品从人胎盘纯化获得。 SDS-PAGE在50kDa和130-160kDa得到两条主要条带。
Disclaimer
推荐在-70℃储存该产品，它能保持稳定2年。

Formation of apical compartments underlies the morphogenesis of most epithelial organs during development. The extracellular matrix (ECM), particularly the basement membrane (BM), plays an important role in orienting the apico-basal polarity and thereby the positioning of apical lumens. Integrins have

The growth properties and self-renewal capacity of embryonic stem (ES) cells are regulated by their immediate microenvironment such as the extracellular matrix (ECM). Integrins, a central family of cellular ECM receptors, have been implicated in these processes but their specific

The severely debilitating disease Congenital Muscular Dystrophy Type 1A (MDC1A) is caused by mutations in the gene encoding laminin-alpha2. Bax-mediated muscle cell death is a significant contributor to the severe neuromuscular pathology seen in the Lama2-null mouse model of MDC1A.
