Ready to use PreciGene 1 kb Plus DNA ladder including 100, 200, 300, 400, 600, 800, 1000, 1500, 2kb, 3kb, 4kb, 5kb, 6kb, 8kb and 10kb. 100 loading
Description
Anunique combination of a number of proprietary plasmids digested withappropriate restriction enzymes and PCR products to yield 19 fragments,suitable for use as molecular weight standards for agarose gel electrophoresis.The DNA includes fragments ranging from 100-10,000 base pairs. The 500, 1.5Kand 3K bands have increased intensity to serve as reference points. Theapproximate mass of DNA in each band is provided (0.86 μg a load) forapproximating the mass of DNA in comparably intense samples of similar size.SourcePCRproducts and double-stranded DNA digested with appropriate restriction enzymes,are phenol extracted and equilibrated to 10 mM Tris-HCl (pH 8.0) and 10mM EDTA.Range: 100-10K bp
Number of bands: 19
Concentration: 172 μg/ml
Package: 86ug / 500ul
Recommended Load: 5 μl / well
Containing orange G, xylene cyanol FFand bromophenol blue as tracking dyes
Storage
Store at 25°C for 6 months

在营养学的范畴里,组氨酸被认为是一种人类必需的氨基酸,主要是儿童。在发育多年之后,人类开始可以自己合成它,在这时便成为非必需氨基酸了。在慢性尿毒症患者的膳食中添加少量的组氨酸,氨基酸结合进入血红蛋白的速度增加,肾原性贫血减轻,所以组氨酸也是尿毒症患者的必需氨酸。 在组氨酸脱羧酶的作用下,组氨酸脱羧形成组胺。组胺具有很强的血管舒张作用,并与多种变态反应及发炎有关。此外,组胺会刺激胃蛋白酶与胃酸。
只有9个氨基酸,分子量1KD左右,想免疫小鼠制备单抗,有没有前辈做过这方面的东西?想了一些方法,但价值不大,请前辈们指教,不甚感激。
没有这8种氨基酸就会发生由于缺乏营养所引起的疾病;氨基酸在医药上也有很大的用途,现在手术中输液都加有各种氨基酸,使患者的抵抗力增强,同时也增加营养。随着人民生活水平的提高,人们对摄入的营养物质的要求越来越高,尤其是幼儿、青少年的健康成长,疾病患者的康复,都迫切需要高质量的营养物质,所以有效开发氨基酸食品是很有必要的。
我在看基因方面的文献。基因位点C802T的氨基酸改变H268Y是什么意思啊。求大神指教
