- SourceHuman VLDL R, His Tag (VLR-H5227) is expressed from human 293 cells (HEK293). It contains AA Gly 28 - Ser 769 (Accession # P98155-2).Predicted N-terminus: Gly 28Request for sequence
- Molecular Characterization

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 84.0 kDa. The protein migrates as 90-110 kDa under reducing (R) condition (SDS-PAGE) due to different glycosylation.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>90% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

- BackgroundThe very-low-density-lipoprotein receptor (VLDL-R) is a lipoprotein receptor that shows considerable similarity to the lowdensity-lipoprotein receptor. VLDL R is a 130 kDa type I transmembrane protein in the LDL receptor family that plays a significant role in lipid metabolism and in nervous system development and function .This receptor has been suggested to be important for the metabolism of apoprotein-E-containing triacylglycerol-rich lipoproteins, such as very-low-densitylipoprotein (VLDL), beta-migrating VLDL and intermediate-density lipoprotein. It is also one of the receptors of reelin, an extracellular matrix protein which regulates the processes of neuronal migration and synaptic plasticity. In humans, the VLDL-R is encoded by the VLDLR gene.A rare neurological disorder first described in the 1970s under the name "disequilibrium syndrome" is now considered to be caused by the disruption of VLDLR gene. The disorder was renamed VLDLR-associated cerebellar hypoplasia (VLDLRCH) after a 2005 study. It is associated with parental consanguinity and found in secluded communities such as the Hutterites. VLDLRCH is one of the two known genetic disorders caused by a disruption of reelin signaling pathway, along with Norman-Roberts syndrome.

最好能说得具体点,小弟对此几乎一窍不通
谢谢
1. 粗纯:将制备抗体的血清或是腹水,细胞上清,直接用盐析法进行处理,这样可以将这些物质里面的其他杂质去掉,获得蛋白的成分,但是由于是粗纯,里面会混有大量的其他蛋白,这样获得的抗体,纯度较低,用于实验中背景比较高。
2.通用型纯化:用抗体结合蛋白Protein A,Protein G或者Protein L。因为不同来源的抗体和这些抗体结合蛋白的结合能力不同,所以需要根据抗体来源选择使用哪种抗体将诶和蛋白最好。对于有一些单链抗体,则多半使用protein L来进行纯化。经过抗体结合蛋白的亲和纯化后,溶液中基本只保留了抗体的成分,其他蛋白都去掉了,抗体纯度可以比较高。相对来说,这种方法是大规模抗体制备中,用得最多的纯化方法,很多抗体公司都采用这种方法来对抗体进行纯化。
3.特异型纯化:但是有些抗体,需要纯度特别高,特异性特别好,就不能简单采用上述两种方法进行纯化了。必须要通过将抗原固定制备成特异的亲和纯化柱,再纯化抗体。这个时候得到的就全是针对一种抗原的抗体了,特异性最好。当然,由于牵涉到抗原固定等操作,成本相应是最高的。
