This GLP-1 (7-36) amide, is labeled with biotin at the peptide N-terminus.GLP-1 (7-36) amide is an incretin hormone that causes glucose dependent release of insulin by pancreaticbeta cells. It is the cleavage product of GLP-1 (1-36) amide peptide (Cat# AS-22460).Both GLP-1 (7-36) andGLP-1 (7-37)-Cat# AS-20761, also play roles in gastric motility (gastric emptying), on the suppression of plasma glucagon levels (glucose production) and possibly on the promotion of satiety and stimulation of glucose disposal in peripheral tissues independent of the actions of insulin. GLP-1 (7-36) has a short half life of less than 2 minutes, and like GIP, is rapidly degraded by the enzyme dipeptidyl peptidase IV (DPP-4),which is widely expressed in a number of sites, including the endothelial cells of small gut arterioles.DPP-4 degrades GLP-1 (7-36) into the non insulinotropic GLP-1 (9-36)-Cat# AS-65070 (some studies suggest it may have weak insulinotropic activity). As a result, the majority of GLP-1 (and GIP) is inactivated as an insulinotrope before reaching the systemic circulation. | |

请问各位大神,配制琼脂糖胶的电泳浓度是怎么设定,比如百分之1或百分之1.5的浓度是怎么设置,是1.5g的琼脂糖粉加100g的TAE麽?
琼脂糖 从琼脂中提取的、由不同类型吡喃半乳糖聚合而成的多糖。在生物化学和分子生物学研究中用于凝胶过滤、凝胶电泳和凝胶扩散实验
琼脂糖是线性的多聚物,基本结构是1,3连结的β-D-半乳呋喃糖和1,4连结的3,6-脱水α-L-半乳呋喃糖。琼脂果胶是由许多更小的分子组成的异质混合物。它们的结构相似,但带硫酸根和羧基组分,凝胶能力差。
琼脂糖(Agarose)的特性详细介绍可以登录生物帮看看, http://www.bio1000.com/news/cp/ 生物产品,生物学新技术,生物研发,生物产业,生命科学创新产品。
biowest agarose 指的是西班牙琼脂糖。
agarose指的是琼脂糖。
注意DNA酶污染的仪器可能会降解DNA,造成条带信号弱、模糊甚至缺失的现象。 电泳洗脱法
低熔点琼脂糖凝胶电泳挖块法
冻融回收法
玻璃奶回收法
柱回收法 将电泳槽用ddH2O反复清洗干净,倒入新鲜配制的灭菌电泳缓冲液;
根据点样量制备合适厚度的琼脂糖凝胶板;
切胶时尽可能切掉不含DNA片段的凝胶;
要尽量减少DNA在紫外下的照射时间以减少对DNA的损伤;
熔胶要完全。向左转|向右转
