I'm looking to test specificity of an assay for insulin and need to find a good source for Human, Rat and Mouse insulin (recombinant and native purified). Can anyone suggest a good company to purchase from?
Thanks, Entedhar, but I'm looking for the analyte to test. I already have kits that are supposed to detect Human Insulin but I need to test cross-reactivity of these kits for sources of Mouse and Rat insulin.
