The PromoKine 3D Cell Culture Matrix Kit (BME) contains a commonly used cell-adhesive matrix with a microporous structure which is derived from animal sources. It provides a very good scaffold for cells to grow in a 3D fashion – enabling mimicking of cellular processes and responses much more similar to natural in vivo environments than 2D cell culture. BME is a more naturally relevant matrix and for example well suited for modeling the morphological effects of early oncogenesis on three-dimensional microenvironments. However, as it is sourced from animals there is certain lot to lot variability and growth factor contamination. PromoKine’s BME is a growth factor-reduced and endotoxin-free matrix.

那糖酵解中依赖NAD的酶不是要在线粒体内反应?
DNMT3a,Dnmt3a,DNMT3A三者有何区别呢,在大鼠或者小鼠身上,用来指酶或者基因时,应该如何表达呢?谢谢
因为溶蛋白酶是蛋白质本质的酶
1、洗碗用的洗洁精,含脂肪酶,能快速水解油脂,还可能含其他酶成分
2、洗头用的洗发水,含脂肪酶,能快速水解油脂,还可能含其他酶成分
3、洗澡用的沐浴露,含脂肪酶,能快速水解油脂,还可能含其他酶成分
4、洗衣用的洗衣粉或洗衣液,含有多种酶,比如脂肪酶、蛋白酶等
除了以上用的频繁外,还有一些可能用到的,
比如某些促进消化的药片,含有脂肪酶、蛋白酶、淀粉酶等
厨房用的嫩肉粉,含有蛋白酶等
胰蛋白酶Trypsin (Parenzyme) 为蛋白酶的一种,EC 3.4.4.4,是从牛、羊、猪的胰脏提取的一种丝氨酸蛋白水解酶。在脊椎动物中,作为消化酶而起作用。在胰脏是作为酶的前体胰蛋白酶原而被合成的。作为胰液的成分而分泌,受肠激酶,或胰蛋白酶的限制分解成为活化胰蛋白酶,是肽链内切酶,它能把多肽链中赖氨酸和精氨酸残基中的羧基侧切断。它不仅起消化酶的作用,而且还能限制分解糜蛋白酶原、羧肽酶原、磷脂酶原等其它酶的前体,起活化作用。是特异性最强的蛋白酶,在决定蛋白质的氨基酸排列中,它成为不可缺少的工具。
明白了么,少年?
