the first times i used the membrane, i observed that the hybridization at some points was weak but after 5-6 uses, it worked perfectly.

This week i´m going to receive a new membrane i hope it works well from the begining.

3 years ago i was working with ISOGEN´s membranes it worked excellent, it´s a shame that they stopped its production.

Dear it was very good , go head with that ocimum biosolution kit
