Wizard DNA Cleanup Kit - Resin Issue

| posted 25 Oct, 2024 02:33
Hi,

I purchased 2 brand new Promega Wizard DNA Cleanup Kit. After warming up, both kits' resins had this black seed/mold-like stuff at the bottom. Is this normal? I added a picture here.

Best,
Rocky

I'e never seen that before, Rocky. I'd be surprised if that was microbial growth since that solution is a very strong denaturant. In any case, it might be worth returning it.

We have found the same black stuff in our Wizard kits. One person used it, and it seemed to work fine. But, have you contacted the company? I was going to do that today.

"The dark gray and black particulates in the Wizard DNA Clean Up resin is not a contaminant. This is a component of the manufacturing of the reagent. In fact,

We provided this note, under appearance, on the Certificate of Analysis for this product:"
