Method of detecting biological materials using a polyvinyllidene fluoride membrane
First Claim
1. A method of detecting a biological material whereby a biological material is adhered to a membrane which is then contacted with a reagent capable of binding to said biological material and capable of being detected, such that the detection of said reagent bound to-said biological material represents a biological material detection signal evidencing the presence of said biological material, and the detection of said reagent directly bound to said membrane represents background noise, wherein the improvement comprises utilizing a polyvinylidene fluoride membrane which has been subjected to a temperature of at least about 80°
- C. but less than the temperature at which the membrane softens and deforms for a time sufficient to substantially reduce said detecting reagent from directly adhering to said membrane, so as to result in a decrease in the background noise and an increase in a biological material detection signal-to-noise ratio.

Abstract
The present invention provides an improved method of detecting or transferring a biological material whereby a biological material is adhered to a membrane which is then contacted with a detecting reagent, wherein the improvement comprises utilizing a polyvinylidene fluoride membrane which has been subjected to a temperature of at least about 80° C. but less than the temperature at which the membrane softens and deforms for a time sufficient to reduce the ability of the detecting reagent to directly adhere to the membrane.
