Information for AAV1 (Catalog # 106176-AAV1)(Back to top)
Purpose
Ready-to-use AAV1 particles produced from pAAV.hSynapsin.SF-iGluSnFR.S72A (#106176). In addition to the viral particles, you will also receive purified pAAV.hSynapsin.SF-iGluSnFR.S72A plasmid DNA.
hSynapsin driven SF-iGluSnFR.S72A, glutamate sensor. The S72A mutant has lower affinity for glutamate. Slower on-rate and faster off-rate. Enhanced temporal resolution and spatial resolution. These AAV preparations are suitable purity for injection into animals.Delivery

Viral Quality Control
- Addgene ensures high quality viral vectors by optimizing and standardizing production protocols and performing rigorous quality control (QC) (see a list of our QC assays). Thespecific QC assays performed varies for each viral lot. To learn which specific QC assays were performed on your lot, please contact us.
- Titer: the exact titer of your sample will be reported on the tube. The titer you see listed on this page is the guaranteed minimum titer. See how titers are measured.

ELISA实验,操作的时候,加入底物,溶液变成蓝色,孵育一段时间后,加入终止液,变成黄色,测吸光值。然后,当天忘记扔板子了,第二天想到去扔的时候,所有孔都变成无色透明的了!!!为什么会褪色???是试剂有问题?还是因为室温太高环境影响?如果是试剂问题那我之前做的结果还能信么?
不同的酶Km值不同,同一种酶与不同底物反应Km值也不同,Km值可近似的反应酶与底物的亲和力大小:Km值大,表明亲和力小;Km值小,表明亲合力大。
Km最小的那个底物,就是酶的最适底物。
我是新手,来到丁香园看到有这么多的热心人,感到很高兴!!我也有很多问题需要大家的帮助!!实验已经作了一年了可是毫无进展,心里很是着急!!
我的课题是以外消旋的苯基乙二醇为底物,用假丝酵母催化生成手性纯的S-型苯基乙二醇,由于是老课题,所以目标是提高转化反应的底物浓度和菌体的使用批次(目前菌体使用一批后便不能再使用)。
我曾试过很多种方法,但均效果不大!我试着在转化过程中添加醛类,酮类,醇类作为辅助底物,增加菌体的使用批次。可效果不好,特别是添加了醇类后还有的起了反作用,因为我的这个转化过程中涉及到NAD和NADPH的再生。(其转化过程是酵母先催化将外消旋的苯基乙二醇变为酮,再将酮还原为醇,经过这一过程就将外消旋的苯基乙二醇变为手性纯的S-型了)
我还试过用固定化的方法,海藻酸钙包埋法,可是这样底物浓度就更低了!!
我现在不知道下一步该如何做了,很着急,请大家帮帮忙。谢谢了!!谢谢
