PLEASE NOTE: During August 2022 we are doing a comprehensive revision of our customer service workflow. This includes training of current and new personnel. We are expecting that these changes will have only very minimal effects on our overall order processing and shipping activities. However, we do ask any customers who prefer that their shipments go out on Fridays to contact our Customer Service group and let them know about your preferences in advance. Thank you.
Reminder: Genuine LC Laboratories® brand PMA, which we have been manufacturing in the U.S. for more
than 40 years, is available directly from us: Cat No. P-1680 Phorbol 12-Myristate 13-Acetate, >99.5%.
Our PMA is also available from our >50 U.S. and international distributors, and from more than a dozen
major biochemical reagent "resellers" (who sell our PMA under their own brand names and labels)
