It cleaves asparagine-linked high mannose as well as hybrid and complex oligosaccharides from glycoproteins. The cleavage site of PNGase F is the amide bond between the N-acetylglucosamine (GlcNAc) inside the protein and the asparagine residue, while converting the asparagine residue in the digested protein to aspartic acid.

It retains the natural enzymatic activity of TEV protease while exhibiting improved tolerance to variations in pH and temperature. TEV Protease is a highly specific cysteine protease, widely utilized for the removal of affinity tags from fusion proteins. It precisely recognizes the seven-amino-acid sequence EXXYXQ↓ (G\/S) and cleaves between the glutamine and glycine\/serine residues. The most commonly recognized sequence is Glu-Asn-Leu-Tyr-Phe-Gln↓Gly. The inclusion of a His-tag at the N-terminus of TEV Protease allows for its efficient removal via Ni-affinity chromatography following digestion, thereby simplifying the purification of the target protein.","brand":"Cleavion","offers":[{"title":"1000 U","offer_id":57188442669431,"sku":"CLV-0222","price":81.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0991\/7097\/6119\/files\/CLV-0222-0-cleavion-product.png?v=1781696415"},{"product_id":"color-prestained-protein-marker-10-180-kda","title":"Color Prestained Protein Marker (10~180 kDa)","description":"Color Prestained Protein Marker (10~180 kDa) is a tri-color pre-stained ready-to-use protein molecular weight standard that contains 10 known molecular weight pre-stained standard proteins with a molecular weight range of 10~180 kDa.
