We offer PBS - Phosphate-Buffered Saline (10X) pH 7.4, RNase-free (Cat. Nos. AM9624 and AM9625), which is molecular biology grade and is certified to be RNase-free. However, it is not sterile and hence is not cell culture-grade.
All our other PBS products (Cat. Nos. 70011xxx, 10010xxx, 70013xxx, 20012xxx) are filter-sterilized using a 0.1 µm filter and are cell culture grade (ready to use directly on cells). However, they are not tested for nuclease activity.
