pACT2 AD说明书

 

pACT2 AD

载体描述: 

pACT2 generates a fusion of the GAL4 AD (amino acids 768881), a HA epitope tag, and a protein of interest (or protein encoded by a cDNA in a fusion library) cloned into the MCS in the correct orientation and reading frame. pACT2, which is derived from pACT, contains a unique EcoR I site in the MCS. The hybrid protein is expressed at high levels in yeast host cells from the constitutive ADH1 promoter (P); transcription is terminated at the ADH1 transcription termination signal (T). The protein is targeted to the yeast nucleus by the nuclear localization sequence from SV40 T-antigen which has been cloned into the 5′ end of the GAL4 AD sequence. pACT2 is a shuttle vector that replicates autonomously in both E. coli and S. cerevisiae and carries the bla gene, which confers ampicillin resistance in E. coli. pACT2 also contains the LEU2 nutritional gene that allows yeast auxotrophs to grow on limiting synthetic media. Transformants with AD/library plasmids can be selected by complementation by the LEU2 gene by using an E. coli strain that carries a leuB mutation (e.g., HB101).

由于中国现在已经对Proliant New Zealand及其牛血清白蛋白打开,Proliant将促进中国诊断、生命科学、疫苗和细胞培养等市场的持续发展。由于人口的不断增长,并且越来越多的中国人关注医疗健康,这些市场的发展十分重要。

Proliant Biologicals以及新西兰牛血清白蛋白生产厂已经准备好服务于中国快速发展的生命科学市场。位于菲尔丁的生产厂已经在新西兰初级产业部(MPI)注册,并获得血清工业协会(ISIA)的可追溯性认证。凭借分别位于新西兰和美国的生产厂,Proliant是*拥有血清工业协会可追溯性认证的牛血清白蛋白生产商。

Proliant是的动物提取物以及可靠、可追溯的牛血清白蛋白(第五组分)生产商。所有的Proliant牛白蛋白源自Proliant收集的USDA/MPI可食用级血浆;并且不含蛋白酶、不含免疫球蛋白、含有极低的内毒素与生物负载,拥有出色的可溶性/可滤性。

Proliant Biologicals是LGI集团旗下公司。LGI集团是食品、保健品、营养品和生物制剂蛋白质成分的厂商。 Proliant与American Protein Corporation、BHJ Corporation 和Boyer Valley Corporation都是Lauridsen Group Incorporated旗下的私有公司。

无脂肪酸牛血清白蛋白产品及应用牛血清白蛋白(无脂肪酸),或者称为无脂肪酸牛血清白蛋白,或者称为Fatty Acid Free bsa,产品不含有或含有极微量的脂肪酸,如Proliant Biologicals公司货号为68700的bsa。常规方法纯化的bsa难以有效去除其结合的脂肪酸。除了特别纯化的bsa产品外,市售的普通bsa试剂含脂肪酸量的范围一般是:每molbsa含0.2~1.5mol脂肪酸。然而,一些生物医学研究要求使用不含游离脂肪酸的bsa,否则bsa所含高浓度的脂肪酸将影响细胞培养、分化、代谢反应、生化测定等。例如,在3t3-l1脂肪细胞分化过程中不能使用普通bsa试剂,否则影响分化和细胞代谢状态;在测定培养的组织细胞释放的游离脂肪酸浓度时,也必须用不含脂肪酸的bsa,否则难以准确测定甘油三酯水解和游离脂肪酸释放。

 

Reagent Grade (Fatty Acid-Free)

Description (Cat. #68700)

Proliant Fatty Acid Free BSA is used where the presence of lipids and fatty acids may cause problems, such as hormone and cholesterol assays. Fatty acid free albumin also provides maximum binding sites for the addition of specific fatty acids for cell culture applications.  Additional applications include, Nucleic Acid-Based Assays, Immunoassays (RIA, EIA, etc.), Immunohematology and Serology.

*Reagent Grade (Fatty Acid-Free) small package sizes (10g – 500g) are currently only offered in the United States, while 1kg and 10kg are available globally.
