13Z,16Z-Docosadienoic acid is a natural ω-6 polyunsaturated fatty acid (PUFA) formed through a 2-carbon chain elongation of arachi donic acid. 13Z,16Z-Docosadienoic acid acts as an agonist of free fatty acid receptor 4 (FFAR4, also known as GPR120) [1].
Free fatty acids act as a source of energy and also function as signaling molecules which involved in regulating energy homeostasis. The endogenous ligands for FFAR4 are ω3-FAs, such as α-LA,DHA and EPA. FFAR4 has been involved in diverse physiological process such as anti-inflammation, insulin sensitization, release of gut peptides and alternation of food preference [2].
13Z,16Z-Docosadienoic acid strongly inhibited the secretion of ghrelin by isolated mouse gastric cells [1]. Dietary n-3 polyunsaturated fatty acids (PUFA) ameliorate several human diseases such as coronary heart disease, autoimmune and inflammatory disorders, diabetes, obesity and cancer [3]. This 20:2 PUFA has already been identified in fish, mammals, plants, and anaerobic fungi.

1、DNA提取问题:现在核算提取试剂盒大部分都是吸附柱法,相信你应该不会操作错误,如果提取之后进行核酸定量结果很低的话,试着再最后一步溶解核算的时候把水稍微加温(37℃就可以了),溶解时间稍微长一些,然后再离心的时候采用分次离心,比如开始你用200ul溶解的话,你可以分两次用100ul水溶解离心,这样可以提高DNA的产率.
2、电泳问题:如果你核酸定量浓度不低的话就考虑电泳问题,电泳的时候加上1kb的marker,如果marker跑不出来说明你凝胶有问题,一般只要marker跑出来了,DNA浓度又比较高,而没有条带这样的现象很少见,DNA提取比较简单而且相当稳定,本人当时做甲基化提取的DNA有一次拿出来电泳忘了放回冰箱了,结果大夏天的在外面放了一天,心怀忐忑的进行了一次电泳,结果条带依然给力,一点都没有降解.
buffer P1:除去RNA
buffer P2:裂解细胞
buffer P3:沉淀DNA
buffer WA、buffer WB:都是洗涤液(这两个之间有什么区别我也不清楚)
TE:溶解DNA.
哪个正规生物公司DNA提取试剂好用,纯,效果好
大家都用过哪些DNA提取试剂盒,能不能推荐几种
而且比较容易买到,同时提取的DNA便于纯化
