    ab20756 staining Insulin + Proinsulin in human pancreas tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with paraformaldehyde, permeabilized with 0.25% Triton X-100 and blocked for 1 hour at 25°C. Samples were incubated with primary antibody (1/100) for 1 hour at 25°C followed by incubation with Cy3®-conjugated streptavidin for 30 minutes in the dark at room temperature. Nuclei were counterstained with DAPI.

I have purchased the Anti-Insulin + Proinsulin antibody [D3E7] (Biotin) (ab20756) from your esteemed company and I am wondering if you can advise me about the best secondary antibody to be used.

This antibody is already conjugated to biotin and therefore does not need a secondary antibody for detection.
What you will need is avidin or streptavidin conjugated to an enzyme or fluorochrome that will bind to multiple sites on the biotinylated...

Have you tested your human insulin assay against the insulin analogs, such as humalog (lispro), novolog (aspart), lantus (glarginine). If so what is the cross-reactivity to these analogs.

Thank you for your inquiry. 
The antibody pair that we use in the Human Insulin ELISA Kit (ab100578) is capture antibody (ab8304) and detection antibody (ab20756).
