蛋白酶 K,分子生物學級 :Proteinase K, Molecular Biology Grade, 2 ml Kit

價格:¥

貨号:P8107S
品牌:NEB

經銷:基因有限公司

蛋白酶 K(分子生物學級)2ml。蛋白酶 K 是一種枯草杆菌蛋白酶相關的絲氨酸蛋白酶,可水解各種肽鍵。蛋白酶 K 的活性範圍寬泛,在溫度 20 - 60℃ 和緩沖液 pH 7.5 -12.0 的範圍内具有最佳活性狀态(1,2)。當反應中含有高于 2% SDS 和 4 M 尿素時活性受到影響(3)。鈣的存在對蛋白酶 K 的熱穩定性很重要,而與其催化反應無直接關系,因此蛋白酶 K 在含有螯合劑(如 EDTA )的反應緩沖液中仍保持活性(4)

胰酶-EDTA:Trypsin-Versene (EDTA) 100ml

價格:¥

貨号:17-161E
品牌:Lonza

經銷: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.

胰酶:Trypsin 100ml

價格:¥

貨号:17-160E
品牌:Lonza

經銷: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.
