A solid phase radioimmunoassay for detection of early pregnancy in the South Indian bonnet monkey Macaca radiata. Journal of Biosciences. 1985 Mar; 7(2): 145-152.http://imsear.searo.who.int/handle/123456789/160314Using an antibody raised in the rabbit to ovine leutenizing hormone β subunit coupled to activated cellulose, a solid phase radioimmunoassay to detect early pregnancy in the South Indian bonnet monkey has been developed. Non-specific inhibition due to serum was eliminated by inclusion of new born calf serum in the assay tubes. The assay is simple, needs only one centrifugation and can be completed in 6 h at room temperature with no false positive results.enChorionic gonadotropinmonkeysolid phase assayovine leutinizing hormoneArticle
