Objective:To validate an enzyme linked immunosorbent assay (ELISA) method for the quantification of rhCNB in long-tailed macaque sera.Methods: The linear,sensitivity,accuracy,precision and recovery were determined using ELISA.Results:The present ELISA method had high linearity within 0.195 ng/ml-12.5 ng/ml,the working curve of rhCNB was Y=15.1X-0.26, R2=0.996 8 , the method showed good sensitivity of 0.195 ng/ml, the accuracy were in the range of 91.9%-108.8%, and the Coefficient of variation ( CV) for inter-assay were 3.55%,1.39%and 4.71%,the intra-assay were 1.59%,3.2%and 3.8%,all less than 10%, the recoveries were in the range of 88.5% -108.3%, <110% .Thus the method was coincidence with requirement.Conclusion:Double antibody sandwich ELISA assay of rhCNB in long-tailed macaque sera has good sensitivity ,accuracy, precision and recovery and it can be used to measure rhCNB concentration in biological samples .
