A review is given about causes of unspecific binding and the possibility of its prevention. Unspecific binding can be caused by: binding of proteins and glycoproteins on cells or tissues by non-covalent links, undesirable antigen-antibody-reactions, non-immune affinity reactions, changes of the charge of antibodies depending on the labelling procedure. A method for fractionation of labelled antibodies by using precipitation with protamine sulphate is described.
本文综述了非特异性结合的原因及其预防的可能性。非特异性结合可能由以下原因引起:蛋白质和糖蛋白通过非共价键与细胞或组织结合、不良的抗原-抗体反应、非免疫亲和反应、抗体电荷因标记程序而发生变化。本文还描述了一种使用硫酸鱼精蛋白沉淀法对标记抗体进行分级分离的方法。
