Product Highlights
- Convenient format - pre-mixed, pre-optimized 2x solutions
- Versatile - suitable for routine PCR applications
- Ready-to-use - reduces contamination risks
- Suitable for TA cloning - leaves "A" overhang
Product Description
BioMix™ is a complete ready-to-use 2x reaction mix containing a stable Taq DNA polymerase. Developed to perform PCR assays of many common genomic and cDNA templates, simply add water, template and primers.
BioMix reduces the time required to set up reactions, thereby minimizing the contamination risks. Greater reproducibility is ensured by reducing the number of pipetting steps that can lead to errors.
BioMix is supplied with additional MgCl2 solution that allows fine-tuning of reactions, if required.
Applications
- Routine PCR applications
- Products suitable for TA cloning

第一类激素作用在靶细胞表面,并不进入细胞内部,而是与细胞膜表面特异的受体结合.这种结合使腺苷酸环化酶激活产生cAMP(一种第二信使),cAMP再去激活细胞内的一些特定系列的酶,从而引起各种生理效应.这是由E.W.Sutherland于1965年提出来的第二信使假说
第二类激素由于是脂溶性的小分子.能直接进入靶细胞,与靶细胞的细胞质中的受体分子结合成"激素-受体复合物",在一定条件下穿过核膜进入核内,与染色质上的一种酸性蛋白质相互作用,促进DNA样板转录相应的mRNA.
mRNA扩散出核膜进入细胞质,导致某种蛋白质(酶)的合成,从而引起这种激素的生理效应.
B、是重要的储能物质,磷脂为构成生物膜的重要成分,固醇为动物细胞膜的构成物质及形成激素等,B错误;
C、蛋白质是细胞代谢的主要结构物质,糖类是细胞代谢的主要能源物质C错误;
D、ATP的结构简式是 A-P~P~P,其中A代表腺苷,腺苷是构成ATP的重要部分,D正确.
故选:D.
