ELISA reagent suppliers help needed!

[jchristn at umich.edu]

Our laboratory is developing ELISA assays for quatitating levels of human IgG 
subclasses. However, we need to know the specificity of our reagents with 
respect to IgG subclass allotype reactivity. Does anyone know of commercial 
suppliers for these reagents or how to go about getting the standards from the 
WHO?

Also, we recently had trouble with KPL laboratories refusing to replace a 
suspect batch of ELISA and western blot substrates that they sent us. Does 
anyone know of suppliers of comparable reagents to their 2-component TMB 
liguid substrate and their 1-component NBT/BCIP liquid substrate?

Please E-mail me directly because I do not have regular access to Usenet.

Thanks in advance,
