Background:
L‑Selectin (Leukocyte Selectin), also known as CD62L, LAM-1, LECAM-1, LECCAM-1, TQ1, Leu-8, MEL‑14 antigen, DREG, and Lymph Node Homing Receptor, a member of the Selectin family, is a cell surface glycoprotein expressed constitutively on a wide variety of leukocytes. Two forms of L‑Selectin have been reported, apparently arising as a result of post-translational modifications. The lymphocyte form shows an apparent molecular weight of 74 kDa, while the neutrophil form is 90‑100 kDa. Human and mouse L‑Selectin share 76% amino acid sequence homology. L‑Selectin plays a role in the migration of lymphocytes into peripheral lymph nodes and sites of chronic inflammation, and of neutrophils into acute inflammatory sites. Acting in cooperation with P-Selectin and E-Selectin, L‑Selectin mediates the initial interaction of circulating leukocytes with endothelial cells that produces a characteristic "rolling" of the leukocytes on the endothelium. This initial interaction involving ICAM-1 and VCAM-1 leads eventually to extravasation of the white blood cell through the blood vessel wall into the extracellular matrix tissue.
R&D Systems位于美国的明尼苏达州,一直致力于生物制品的开发与生产。公司成立之初主要生产用于医院及临床应用的血控品。1997年,公司推出第一个产品--富血小板血浆质控品;1981年,公司成为全球第二家生产含血小板全血控品的供应商。40多年的发展中,R&D Systems仍持续开发各种血控品产品。 1985年,作为公司推出的第一个科研试剂产品,也是全球第一家将该产品进行商业化生产的产品,R&D Systems成功上市了TGF-beta1蛋白。作为胞外信号分子,TGF-beta1蛋白在多种细胞中进行表达,并作为胞外信号分子参与免疫功能,细胞增殖和细胞分化等生物学过程。该产品推出后,公司陆续从生物材料中纯化了几种细胞因子产品并推向市场。 天然蛋白类产品的成功推广,加速了R&D Systems在细胞因子市场的开拓。公司于1985年形成Growth Factor事业部(现Biotechnology事业部)。Biotechnology事业部的目标是生产和营销重组人细胞因子。与天然来源提取蛋白相比较,DNA重组技术生产的蛋白产品其成本更低,产量更高,完全摆脱原料的限制。1989年,Biotechnology事业部开始开发抗细胞因子的单克隆和多克隆抗体,并于1990年开发了第一个ELISA试剂盒。 2014年2月10日,R&D Systems的母公司宣布命名为Bio-Techne. Bio-Techne旗下包括R&D Systems, Novus Biologicals, BiosPacific, Tocris Bioscience, Boston Biochem和Bionostics。
