Rhinohide polyacrylamide gel strengthener improves upon classic polyacrylamide gel technology by making gels much stronger, providing easier handling and resistance to tearing, without adverse side effects. Rhinohide polyacrylamide gel strengthener is highly recommended for low-percentage gels, large-format gels and gels subject to multiple staining and handling steps. Rhinohide polyacrylamide gel strengthener is also available in a kit (R-33410), which includes an acrylamide/bis-acrylamide mixture (37.5:1 ratio).
