MALDI matrix
LaserBio Labs MALDI matrices cover a wide array of protein and peptide-based applications as well as other chemical families. All our matrices are recrystallized for highest purity and best analytical performance. They are offered in both bulk amounts and pre-weighted aliquots ready to use for daily convenience and fast sample preparation
