Product overview
Product Description HRP-conjugated Goat Anti-Mouse IgG
Applications 1/ 5000-100000 for ELISA
1/ 500-5000 for Immunohisto/cytochemistry
1/ 20000-200000 for Western blotting with ECL substrates
Conjugate HRP
Concentration 0.8 mg/ml
Fluorophore/Peroxidase/Biotin-SP Peroxidase:Purified from horseradish root
Stabilizer 15 mg/ml Bovine Serum Albumin (IgG-Free, Protease-Free)
Purity The antibody was purified from antisera by immunoaffinity chromatography using antigens coupled to agarose beads
Based on immunoelectrophoresis and/or ELISA, the antibody reacts with whole molecule mouse IgG. It also reacts with the light chains of other mouse immunoglobulins. No antibody was detected against non- immunoglobulin serum proteins. The antibody may cross-react with from other species.

如何选择二抗
通常情况下,某一实验中可能同时有几种二抗可供选择,如何能选择到最适合该实验的二抗,需要综合以下几个方面进行考虑:
一、一抗的种属来源
一抗是什么物种来源的,相应的二抗也要是抗该物种的抗体。
二、一抗的免疫球蛋白亚型
二抗需与一抗的类别或亚型相匹配。例如一抗是IgM,则须选择抗IgM的二抗。如果一抗是某一亚型(如IgG1、IgG2a、IgG2b、IgG3、IgG4等),则可选择能与所有亚型结合的抗IgG二抗,也可选择专门针对该亚型的二抗。
三、实验方案
根据实验,选择酶标记(如HRP)的二抗,还是荧光素标记的二抗。根据仪器的激发光和检测通道,选择合适的荧光素。
四、选择哪种形式的二抗,是整个分子还是F[ab’]2片段? 整个IgG分子:此种抗体适用于多数情况。
F[ab’]2 片段:该抗体由 2 个二硫键连接的 Fab 片段组成,用于特定的情况中,如需要避免抗体与具有
Fc 受体的细胞结合,降低非特异性背景。
