本产品中胰蛋白酶和Lys-C 蛋白酶是重组表达的金属蛋白酶。胰蛋白酶超快速特异性裂解精氨酸 (R) 和赖氨酸 (K) 的 C 端肽键;Lys-C 蛋白酶快速特异性裂解赖氨酸 (K) 的 C 端肽键。由于胰蛋白酶不能以相同的速率酶解精氨酸和赖氨酸,造成许多赖氨酸的漏切,同时有的赖氨酸有 PTM 修饰或 C 端紧邻强疏水性氨基酸 (例如 P), 也会造成漏切问题。胰蛋白酶/Lys-C 复合蛋白酶适合处理难酶解消化的复杂蛋白样品。用于蛋白表征、单细胞组学和大队列蛋白组学研究。 溶解液:40μl 50mmol 醋酸溶解,即浓度 0.5μg/μl pH 值范围:复合蛋白酶在 pH7-9 活性最佳 酶切方法: 适用酶切缓冲溶液: 20mmol Tris,50mmol ABC 或 HEPES 缓冲液;pH 值在 7-9 范围内。 变性蛋白样品:按照 1:50 蛋白酶和蛋白量使用,酶切反应蛋白浓度控制在 0.5μg/μl, 37℃干浴孵育 30min。
This product contains trypsin and Lys-C protease, which are recombinantly expressed metalloproteases. Trypsin specifically cleaves peptide bonds at the C-terminus of arginine (R) and lysine (K) residues with ultra-fast kinetics; Lys-C protease specifically cleaves peptide bonds at the C-terminus of lysine (K) residues rapidly. Since trypsin cannot digest arginine and lysine at the same rate, many lysine residues are missed. Additionally, post-translational modification (PTM) on lysine or adjacent strongly hydrophobic amino acids (e.g., proline, P) at the C-terminus can also cause missed cleavages. The trypsin/Lys-C protease cocktail is suitable for processing complex protein samples that are difficult to digest. It is applied in protein characterization, single-cell omics, and large-cohort proteomics research. Reconstitution Solution: Reconstitute with 40 μL of 50 mmol/L acetic acid to obtain a concentration of 0.5 μg/μL. pH Range: The protease cocktail exhibits optimal activity at pH 7–9. Digestion Protocol: Recommended Digestion Buffer: 20 mmol/L Tris, 50 mmol/L ABC, or HEPES buffer (pH 7–9). Denatured Protein Sample: Use a protease-to-protein ratio of 1:50 (w/w). Adjust the protein concentration in the digestion reaction to 0.5 μg/μL, and incubate in a dry bath at 37°C for 30 minutes.
