BackgroundThe defined antibody specificity is directed to the major isotypes of the monkey immunoglobulin system and to the surface determinants of the common Fab portion as tested against as tested in immunoelectrophoresis and double radial immunodiffusion (Ouchterlony). The cytochemical grade allows the use in different types of highly sensitive immunoassays on appropriately treated cell and tissue substrates; in radioimmunoassay; for the production of immunoconjugates with a selected marker; to prepare immunoaffinity adsorbents by coupling to an artificial carrier; in non-isotopic methodology based on solid phase immunochemistry (e.g. ELISA), both as catching antibody and detection reagent; in Western blotting. This product is not pre-diluted. The optimum working dilution of each product should be established by titration before being used.
SourceHighly purified IgG, IgA and IgM isolated from Rhesus monkey serum. Freund’s complete adjuvant is used in the first step of the immunization procedure.
ProductPurified hyperimmune rabbit IgG lyophilized from a solution in phosphate buffered saline (PBS, pH 7.2). No preservative added, as it may interfere with the antibody activity It is reconstituted by adding 1 ml sterile distilled water, spun down to remove insoluble particles, divided into small aliquots, frozen and stored at or below -20°C.
Formulation: Purified hyperimmune rabbit IgG lyophilized from a solution in phosphate buffered saline (PBS, pH 7.2). No preservative added, as it may interfere with the antibody activity
SpecificityPurified IgG fraction of polyclonal Rabbit antiSerum to Monkey immunoglobulins IgG, IgA, IgM, heavy and light chains
Species Reactivity: Inter-species cross-reactivity is a normal feature of antibodies to immunoglobulins, since Ig of different species frequently share antigenic determinants. Precipitation reactions have been observed with immunoglobulins in Serum of other old-world Monkeys, including Cercopithecus, Cynomolgus and Baboon. The antiSerum may also react with other species as has been observed for Chimpanzee and man.
ApplicationsIndirect immunofluorescence,ELISA,Dot blot,Immunoblotting.
StorageThe lyophilized product is shipped at ambient temperature and may be stored at +4°C; prolonged storage at or below -20°C.Prior to use, an aliquot is thawed slowly at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance of the product.
CautionThis product is intended FOR RESEARCH USE ONLY, and FOR TESTS IN VITRO, not for use in diagnostic or therapeutic procedures involving humans or animals. It may contain hazardous ingredients. Please refer to the Safety Data Sheets (SDS) for additional information and proper handling procedures. Dispose product remainders according to local regulations.This datasheet is as accurate as reasonably achievable, but Exalpha Biologicals accepts no liability for any inaccuracies or omissions in this information.

1.单克隆抗体的优点:
(1)杂交瘤可以在体外“永久”地存活并传代,只要不发生细胞株的基因突变,就可以不断的生产高特异性、高均一性的抗体.
(2)可以用相对不纯的抗原,获得大量高度特异的、均一的抗体.
(3)由于可能得到“无限量”的均一性抗体,所以适用于以标记抗体为特点的免疫学分析方法,如IRMA和ELISA等.
(4)由于单克隆抗体的高特异性和单一生物学功能,可用于体内的放射免疫显像和免疫导向治疗.
2.单克隆抗体的局限性:
(1)单克隆抗体固定的亲和性和局限的生物活性限制了它的应用范围.由于单克隆抗体不能进行沉淀和凝集反应,所以很多检测方法不能用单克隆抗体完成.
(2)单克隆抗体的反应强度不如多克隆抗体.
(3)制备技术复杂,而且费时费工,所以单克隆抗体的价格也较高.
抗原有两个基本特性,即抗原性和免疫原性。有抗原性的物质不一定有免疫原性,所以由此引出半抗原和完全全抗原,半抗原必须经过经过一定的改造(偶联蛋白载体BSA,OVA或者HSA等大分子物质)方能成为完全。一般而言完全抗原分子量越大(大于10KDa),结构越复杂引起免疫反应的能力也就越强。
抗体就是能与特异性抗原结合的免疫球蛋白,抗体一般分为多克隆抗体和单克隆抗体,多克隆抗体能与抗原的多个表位结合。本篇主要讲述兔来源的多克隆抗体的生产步骤
多抗一般制备流程:完全抗原的准备→兔子的免疫→ 效价检测和终放→抗体亲和纯化→抗体的浓缩和保存。
又由于自然存在的抗原大都存在多个抗原表位,会刺激机体产生多种针对同一抗原的不同抗原表位相应的不同抗体.
一般来说多克隆的阳性率高一些,但出现假阳性的比例也高一些。
其次,察看次目的蛋白的存在形式,有没有多聚体形式及变构形式;
最后,查看多家抗体公司的DATA,看看别人的WB做出来的条带的位置。
根据你说的,特异识别多个组织中的同样大小的条带,我觉得很可能就是你的目的蛋白。
