To prepare a laminin solution, we recommend that the L6274 be thawed at 2-8°C to avoid the formation of a gel. This can be further diluted in a balanced salt solution. If the product has been thawed at room temperature and ends up as a gel, it cannot be reactivated for use.

应用
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。
生化/生理作用
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。
组分
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。
注意
推荐在-70℃储存该产品，它能保持稳定2年。
制备说明
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。

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 properties of epithelial cells within tissues are regulated by their immediate microenvironment, which consists of neighboring cells and the extracellular matrix (ECM). Integrin heterodimers orchestrate dynamic assembly and disassembly of cell-ECM connections and thereby convey biochemical and mechanical information

The v-Crk protein was originally isolated as the oncogene fusion product of the CT10 chicken retrovirus. Cellular homologues of v-Crk include Crk, which encodes two alternatively spliced proteins (CrkI and CrkII), and CrkL. Though CrkI/II proteins are elevated in several

A key molecular link between cells and the extracellular matrix is the binding between fibronectin and integrins alpha(5)beta(1) and alpha(v)beta(3). However, the roles of these different integrins in establishing adhesion remain unclear. We tested the adhesion strength of fibronectin-integrin-cytoskeleton linkages

Is Product L6274, Laminin from human placenta, laminin 1 or 2?
1 answer-
Fifteen laminin trimers have been identified. We do not determine what type of laminin this is. Typically laminin from placenta is considered laminin-2/4 and laminin from Engelbreth-Holm-Swarm murine sarcoma basement membrane is laminin-1.
