CinderBio offers two unique HTA-Proteases that generate orthogonal data sets

How Vesuvius and Krakatoa are similar and different

Our enzymes-graphics.png

CinderBio’s HTA-Proteases Vesuvius and Krakatoa are both classified as ‘thermopsin’ proteases and derived from different species of acid and heat loving Archaea. Both enzymes show a cleavage preference for E, L, and F amino acids and result in significantly different peptide and protein identifications. Digestion of K562 cell extracts reveals only 11% of peptide and 63% of protein identifications are common to both enzymes. Vesuvius and Krakatoa are compatible with simultaneous co-digestion and sequential digestion of the same sample.

HTA-Proteases are shipped ready-to-use, store ambiently for >2 years, and reaction conditions (80° C, pH 3) obviate the use of chaotropes and alkylating agents. Both HTA-Proteases are particularly effective for membrane and nucleoproteins and have no observable autolysis.
