Human LSAMP HEK293 Overexpression Lysate: 产品信息

产品描述
This Human LSAMP overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of LSAMP protein (Cat: 12136-H02H) from the overexpression lysate was verified.

蛋白构建信息
A DNA sequence encoding the human LSAMP (Q13449) (Met 1-Asn 315), without the pro peptide, was was fused with the Fc region of human IgG1 at the C-terminus.
分子量
The secreted recombinant human LSAMP/Fc is a disulfide-linked homodimer. Yhe reduced monomer consists of 528 amino acids and has a predicted molecular mass of 59 kDa. As a result of glycosylation, the apparent molecular mass of rhLSAMP/Fc monomer is approximately 80-85 kDa in SDS-PAGE under reducing conditions.

Human LSAMP HEK293 Overexpression Lysate: 使用指南

制备方法
Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors (Sigma). Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (Bio-Rad protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
裂解缓冲液
Modified RIPA Lysis Buffer: 50 mM Tris-HCl pH 7.4, 150 mM NaCl, 1mM EDTA, 1% Triton X-100, 0.1% SDS, 1% Sodium deoxycholate, 1mM PMSF.
使用建议
1.  Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube. 2.  Re-dissolve the pellet using 200μL pure water and boil for 2-5 min.
缓冲液
1 X Sample Buffer (1 X modified RIPA buffer+1 X SDS loading buffer).
稳定性 & 储存条件
Store at 4℃ for up to twelve months from date of receipt. After re-dissolution, aliquot and store at -80℃ for up to twelve months. Avoid repeated freeze-thaw cycles.
应用
Western Blot (WB)
Optimal dilutions/concentrations should be determined by the end user.

LSAMP 背景信息

The limbic system-associated membrane protein (LAMP) is a cell surface glycoprotein expressed by cortical and subcortical regions of the mammalian CNS that comprise or receive direct projections from limbic system structures. The 64-68-kDa glycoprotein limbic system-associated membrane protein (LsAMP) is expressed on the surface of somata and proximal dendrites of neurons. These areas perform cognitive and autonomic functions, also learning, and memory. The functional analysis indicates that LsAMP acts as a selective adhesion molecule, serving as a guidance cue for specific patterns of connectivity, which underlies the normal development of the limbic system. In animal studies there has been found that rats with an increased level of anxiety had 1.6-fold higher expression of the LsAMP gene in the periaqueductal gray compared to rats with a low level of anxiety, indicating a possible role of LsAMP in the regulation of anxiety.
