chromatec成立于1999年,是一家致力于提供不同的凝血診斷領域人類和重組蛋白的生物技術公司。此外,chromatec還在蛋白質組學領域提供不同的服務。chromatec的產品普遍被quan球范圍內的大學、生物技術公司、制藥公司和研究機構所使用,并通過了DIN EN ISO 9001:2015認證。
主要生產線
(1)人血小板因子4(Platelet Factor 4 human)
血小板因子4(PF4;也稱為CXCL4)在巨核細胞和血小板中合成。血小板因子 4是一種由70個氨基酸組成的蛋白質,由活化血小板的α顆粒釋放。它的主要生理作用似乎是中和血管內皮表面的分子,從而抑制局部抗凝血酶III活性并促進凝血。作為中性粒細胞和成纖維細胞的強化學引誘劑,PF4可能在炎癥和傷口修復中發揮作用。Oncostatin-A是CXC趨化素家族的成員。人PF4用于證明誘導的血小板減少癥。此外,它還用作腫瘤治療期間血管生成的抑制劑。
chromatec提供重組人血小板因子4、親和素標記的人血小板因子4、人血小板因子4重組變體、以及抗人血小板因子4抗體系列產品。
(2)顆粒溶素(Granuylsin)
顆粒溶素(GNLY)是細胞毒顆粒蛋白,與穿孔素和顆粒酶共同定位于人的細胞毒T淋巴細胞(CTL)和自然殺傷細胞(NK)溶細胞顆粒中,也釋放至健康人和患者外周血中。GNLY是機體抵抗多種病原微生物和殺滅腫瘤細胞的重要物質。
(3)血小板膜糖蛋白II b / III a(glycoprotein II b / III a)
chromatec提供分離自人血小板的血小板膜糖蛋白II b / III a。
