Please note this product is NOT P81 paper. We have not stockpiled P81 but can now produce an equivalent product. It does NOT have exactly the same properties as P81.

Due to the paper base (Grade 541 from GE Healthcare cat#1541-917), we know our derivatised product suffers from spot spreading, meaning this may be incompatible for 96 well plate assays. We can supply a free sample sheet for you to test.

Other limitations will be listed here as we learn about applications and receive more feedback. Our aim is to provide this vital resource to the research community for an affordable price.
