商品描述

General Category:

    Antigens » Tumor Markers

Disease Category:

    Tumor Markers » Antigens
Source:
Human seminal fluid.Blood sample from donor was tested and found negative for HBsAg, HIV-1 and HIV-2 antibodies, and HCV.
Applications:
PSA is a protein produced by both normal and abnormal prostate cells. The PSA level in the blood may be elevated in men who have a benign or a malignant (cancerous) growth in the prostate. PSA is suitable for use as a standard in immunoassay for screening and monitoring of prostatic neoplasia, immunogen for antisera production, and tracer for iodination.
Analysis:
Purity > 98 % (SDS-PAGE).Immunological identity confirmed by reaction with PSA specific monoclonal antibody.
Presentation:
Lyophilized from 5% mannitol, 10 mM Na-acetate, 0.15 M NaCl, pH 5.6.Product is recommended to reconstitute with distilled water.
Storage Conditions:
-20 °C (between -15 and -30 °C allowed)

This product is sold for research use only. Standard Laboratory Practices should be followed when handling this material.
Advanced immunochemical高敏C反应蛋白人C反应蛋白(CRP)是所谓的急性期蛋白之一。它在血液中的浓度随着对炎症的反应而迅速增加。CRP是224个残基蛋白,单体分子量约为25 kDa,pI 6.4(1-4)。它属于五味子毒素,这是一种进化保守的蛋白质家族,其特征在于钙依赖性配体结合和五个单体的对称性,这些单体在中心孔周围形成一个环(5)。CRP在体内的确切功能尚不完全清楚。已证明CRP参与炎症以及先天免疫过程。CRP的重要生物活性取决于其与各种配体(例如受损细胞膜,凋亡细胞和纤连蛋白)的结合能力,对磷胆碱残基的亲和力最高。当CRP与配体结合时,它可以被补体成分C1q识别,从而激活经典补体途径。另一方面,CRP通过与补体因子H相互作用来调节替代补体途径
