Kirkegaard & Perry Labs has developed a new liquid ELISA substrate for
alkaline phosphatase based on BCIP chemistry. It is more sensitive than
pNpp and eliminates the need for tablets. If you would like to sample
this substrate, please contact me at KPL (800-638-3167 x143 or
301-948-7755 x143) or send an e-mail.
