Protease 'GingisREX (RgpB)'

Specifically cleaves proteins at arginine! It also cleaves when the adjacent amino acid is proline!

"GingisREX (RgpB)" is an arginine-specific protease that cleaves proteins at the C-terminal of arginine residues. It is capable of cleaving arginine-proline sequences, which are difficult to cleave with other enzymes. This enzyme is useful for peptide mapping, de novo peptide sequencing, and the analysis of post-translational modifications. 【Features】 - Cleavage is possible even when the adjacent amino acid is proline. - Compared to cleavage by trypsin, longer peptides are generated, allowing for separation and identification using high-resolution MS. - Increases options for sample preparation for bottom-up approaches, improving degradation profiles and sequence coverage. - Shows activity over a wide pH range of 5.0-9.0, requires cysteine, but is inhibited by guanidine hydrochloride. *For more details, please refer to the PDF document or feel free to contact us.*
