應用
水溶液可以直接用于衍生化，而无需事先进行透析或凝胶渗透色谱法。
生化／生理作用
β-半乳糖苷酶可将乳糖切割成单糖成分（葡萄糖和半乳糖）。它还在反馈环中催化葡萄糖转糖基化为β-半乳糖苷酶的诱导物 - 异乳糖。

A sensitive and specific double-antibody enzyme immunoassay (EIA) for a thyrotropin releasing hormone (TRH)-like immunoreactive substance has been developed. In order to synthesize TRH-labeled beta-D-galactosidase (beta-gal), a newly devised TRH derivative, pGlu-His-Pro-NH-(CH2)6-NH2 (TRH-Hex), was employed. TRH-Hex was linked to beta-gal

Rabbit immunoglobulin G (IgG) was reduced by incubating with 10 mM 2-mercaptoethylamine and then treated with excess amounts of N,N'-o-phenylenedimaleimide. As a result, maleimide residues were introduced into rabbit IgG molecules. Rabbit IgG containing maleimide residues could be coupled to
