Used in research settings to quantitatively measure levels of bovine optophotoprotein (OPTC) in biological samples such as serum, plasma, or tissue homogenates. This ELISA kit is particularly useful in studies related to eye health and retinal function in bovines, helping researchers investigate conditions associated with photoreceptor integrity and ocular diseases. The assay enables high sensitivity and specificity, making it suitable for monitoring OPTC expression changes in experimental models, supporting veterinary research and development of diagnostic tools for bovine ocular disorders.
