Overview

MeltiLex™ is a solid scintillant alternative to liquid scintillation cocktails for Filtermat samples. MeltiLex is a unique melt-on scintillator for dry on support counting for use with Filtermat.

  • MeltiLex A – used with Filtermat A (catalog number 1450-421). GF/C filters are thin, and typically used for whole cell assays such as 3H-thymidine incorporation assays.
  • MeltiLex B – used with Filtermat B (catalog number 1450-521). GF/B filters are typically used in cell-membrane based assays, such as receptor-ligand binding assays.

The Filtermat -plus-cocktail combination provides increased tritium counting efficiency. In a thymidine uptake experiment, the relative counting efficiencies of Filtermat with MeltiLex and HARVEST Plate with cocktail are 53% and 68%, respectively. Both methods exhibited similar consistencies in count rate and therefore harvesting efficacy. Results from the two-dilution series also showed excellent correlation.
