Especially for use in ligand receptor binding, Filtermat B is similar to Filtermat A (a glassfibre filtermat printed on both sides) but twice as thick. It is possible to load more material onto this filter and, if long presoak times are required, it is strong enough for easy handling when wet.Filtermat B is a 24-position, glassfibre filtermat printed on both sides, similar to Filtermat A but double the thickness. It is suitable for harvested and pipetted samples and is specially designed for ligand receptor binding studies. It is possible to load more material onto this filter and, if long presoak times are required, it is strong enough for easy handling when wet.
