Neuromab是一家由NIH资助成立的单克隆抗体库。

The UC Davis/NIH NeuroMab Facility is a national monoclonal antibody-generating resource funded by the National Institutes of Health (NIH). The mission of the UC Davis/NIH NeuroMab Facility is to provide a unique neuroscience-based approach to generating mouse monoclonal antibodies optimized for use in mammalian brain (NeuroMabs). NeuroMabs are generated from mice immunized with synthetic and recombinant immunogens corresponding to components of the neuronal proteome as predicted from genomic and other large-scale cloning efforts. Comprehensive biochemical and immunohistochemical analyses of human, primate and non-primate mammalian brain are incorporated into the UC Davis/NIH NeuroMab Facility screening procedure. This yields a subset of mouse mAbs that are optimized for use in brain (i.e., NeuroMabs): for immunohistochemical- based imaging studies of protein localization in adult, developing and pathological brain samples, for biochemical analyses of subunit composition and post-translational modifications of native brain proteins, and for proteomic analyses of native brain protein networks.

Neuromab的主要产品包括：

Array Tomography

Dendritics公司主要关注人类树突状细胞，希望找到能够促使CD34+造血前体细胞转化为树突状细胞（在GM-CSF和TNF-alpha存在的情况下）的细胞因子。在1992-2005年间，大量的研究使得研究者对人类树突状细胞的产生、细胞通路、C-type凝集素受体的功能及Toll-like受体的活性有了更深的理解。

DENDRITICS was started in 2005 by former members of SCHERING PLOUGH Laboratory for Immunological Research (LIR) in Dardilly, France. From their long experience at LIR, the team members of DENDRITICS have gathered complementary scientific and technological knowledge in different areas of immunology. The initial focus of LIR was in the biology of B lymphocytes, elaboration of human monoclonal antibodies, and in cytokine discovery (IL-3, IL-4, IL-7, IL-10, IL-17, GM-CSF) together with our colleagues of DNAX Research Institute in Palo Alto, California.

Our interest in cytokines led to the finding that human dendritic cells (DCs) could be generated in vitro from CD34+ hematopoietic progenitors cultured in the presence of GM-CSF and TNF-alpha.

The period from 1992 to 2005 saw the specialization of LIR in DC biology and was fuelled by a large-scale effort to discover and study the function of genes specifically expressed by these cells. This program led to a number of findings that contributed in particular to understanding the heterogeneity of DCs, the pathways regulating DC migration, the function of C-type lectin receptors in DCs and the activity of Toll-like receptors in DCs. Many novel genes were discovered through screening of cDNA libraries or through monoclonal antibodies raised against DCs.

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。1977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。
