bldbnkr Posted September 6, 2019 Share Posted September 6, 2019 Hi Immucor users, Has anyone noticed a new lot number of CorQC Antisera is not reacting well with Screening cell #3? It appears that the Anti-c component of the mixture is not as strong. I am wondering if anyone has contacted the manufacturer for a recall/replacement? Thank you!

Texas Lynn Posted September 9, 2019 Share Posted September 9, 2019 (edited) yes, we have noticed it just last week, but we have not called it in to Immucor. Edited September 9, 2019 by Texas Lynn added Link to comment Share on other sites More sharing options...
David Saikin Posted September 10, 2019 Share Posted September 10, 2019 be nice to know the lot#. I use CorQc for gel, so I've diluted the antisera anyway (always 4+, even at 1:20). Link to comment Share on other sites More sharing options...

sgoertzen Posted September 12, 2019 Share Posted September 12, 2019 I notified my Immucor rep but he wants to know what lot # CorQC is everyone having problems with? bldbnkr, Texas Lynn, David? Link to comment Share on other sites More sharing options...
David Saikin Posted September 17, 2019 Share Posted September 17, 2019 (edited) They sent me a different lot: I got the same results (after years of testing using this reagent). Am kind of at a loss for progressing until I hear more from them. Lots: 30816 & 31825 Edited September 17, 2019 by David Saikin added lot #s Link to comment Share on other sites More sharing options...
