- how to know if a gene is a transcription factor?
- 热度 1
- To qualify as a transcription factor, a protein must possess two qualities. 1) Ability to bind to DNA and 2) recruit RNA polymerase/alter transcription of a gene. The most common GTFs are TFIIA, TFIIB, TFIID (see also TATA binding protein), TFIIE, TFIIF, and TFIIH . ...
- PCR中DMSO该加多少浓度可以提高反应的特异性？
- 一般而言，加入终浓度2.5%的DMSO可增加PCR的特异性。KJ建议加终浓度为5%的DMSO，可降解二聚体结构产生的可能。

- what is S-cone?
- Conventional trichromatic color vision models1 postulate that long- (L), middle- (M), and short-wavelength (S) cone signals reorganize into two color-opponent channels where L+S (red) and M (green) cone signals cancel each other, and L+M (yellow) and S (blue) cone signals cancel each other.

- 人体pH值，胰蛋白酶(trypsin)的溶解和抑制活性，1M tris-HCL PH=8.0 母液的稀释
- 人体内的 pH值 篇首 : 化学上用pH值来表示酸碱强度.当pH为7即为中性,小于7时为酸性,大于7时为碱性。而人的血液pH值为7.35～7.45.由于血液是弱碱性的，因此在它的流域内，大多数体液也表现程度不同的碱性，如唾液和眼球内液pH值为7.2；脑脊液、胆汁都是7.4；小肠液为7.6；胰液为8，有时高达 8.3～8.4；大肠液 ...
