(1)非抗體柱純化，產(chǎn)品中無任何其它抗體如IgG等的污染。 (2)pH耐受范圍廣，可耐受0.5 M NaOH和0.5M HCl 處理，不降解，抗體結合能力不變。 (3)產(chǎn)品有特為抗體純化柱設計的連接基團，可直接用于蛋白A柱的制備。 (4)具有生產(chǎn)規(guī)模大，質量穩(wěn)定，純度高等優(yōu)點。 重組蛋白A可偶聯(lián)到固體分離介質（如agarose）上，用于單克隆抗體或多克隆抗體的純化。重組蛋白A可與多種報告分子（熒光染料、酶標記、生物素、膠體金、放射性標記等）偶聯(lián)并不影響其與抗體結合的活性。這些偶聯(lián)后的蛋白A衍生物可用于Western-blot、ELISA、免疫組化等的抗體檢測。

The recombinant Protein A is a genetically engineering protein containing IgG-binding domains.Recombinant Protein A is ideal for purification of polyclonal or monoclonal IgG antibodies. Protein A binds to most human and mouse IgG subclasses (e.g., human IgG1, IgG2, IgG4; mouse IgG2, IgG2a, IgG2b,IgG3). It also binds to cow, guinea pig, hamster, house, pig and rabbit total IgG form.Recombinant protein A can be coupled to solid separation medium (such as agarose) for monoclonaland polyclonal antibody purification. Recombinant protein A can be coupled to a variety of molecules (such as fluorescent molecules, enzyme markers, biotin, colloidal gold and radioactive markers). These coupled derivatives can be used in antibody test in the process of Western-blot, ELISA or immunohistochemical tests.
