Resazurin dye-based colorimetric assay is simple and cost-effective to evaluate viability and cytotoxicity. This dye also used for evaluating proliferative responses of PBMCs against mitogens and antigens especially to assess the CMI response against vaccines and pathogens. However, the assay needs to be optimized for different cell types and animal species. So far, resazurin based assay is not available for sheep and goats. In the present study, the assay was optimized for PBMCs of goat with two density gradients viz., Histopaque and , and different culture conditions. | Resazurin based colorimetric proliferation assay for PBMCS of goats and sheep
