蛋白酶 K,分子生物学级 :Proteinase K, Molecular Biology Grade, 2 ml Kit

价格:¥

货号:P8107S
品牌:NEB

经销:基因有限公司

蛋白酶 K(分子生物学级)2ml。蛋白酶 K 是一种枯草杆菌蛋白酶相关的丝氨酸蛋白酶,可水解各种肽键。蛋白酶 K 的活性范围宽泛,在温度 20 - 60℃ 和缓冲液 pH 7.5 -12.0 的范围内具有最佳活性状态(1,2)。当反应中含有高于 2% SDS 和 4 M 尿素时活性受到影响(3)。钙的存在对蛋白酶 K 的热稳定性很重要,而与其催化反应无直接关系,因此蛋白酶 K 在含有螯合剂(如 EDTA )的反应缓冲液中仍保持活性(4)

胰酶-EDTA:Trypsin-Versene (EDTA) 100ml

价格:¥

货号:17-161E
品牌:Lonza

经销:基因有限公司

Trypsin-EDTA (ethylenediaminetetraacetic acid) is a combined reagent used to remove cells from the culture vessel surface into suspension. The EDTA, a chelator of divalent cations, is added to trypsin solutions to enhance activity. The calcium and magnesium in the extracellular matrix, which aids in cell-cell adhesion, also obscures the peptide bonds that trypsin acts on. The EDTA is added to remove the calcium and magnesium from the cell surface which allows trypsin to hydrolyze specific peptide bonds. This activity can be halted by adding a serum media mixture, or a Trypsin inhibitor (from soybean, for example) in serum-free systems. It is supplied at use dilution. 17-161 contains 0.5 grams per Liter Trypsin 1:250, 0.2 grams per liter Versene (EDTA). Porcine parvovirus tested and mycoplasma screened. Product is manufactured with irradiated trypsin.

2.5% Trypsin-EDTA Solution 10X is a concentrated solution that can be diluted to the 1x working concentation. This product is made from trypsin powder (1:250) extracted from porcine pancreas.

胰酶:Trypsin 100ml

价格:¥

货号:17-160E
品牌:Lonza

经销:基因有限公司

a clear, colorless-yellow, highly active porcine enzyme preparation, used to remove cells from the culture vessel surface into suspension. It is generally used at a working concentration of 0.25%, prepared in a balanced salt solution, without calcium or magnesium at a pH of 7.6-7.8. After treatment, trypsin activity can be halted by adding a serum media mixture or a Trypsin inhibitor (from soybean, for an example) in serum-free systems.
