LSAMPProtein Product Information
Synonym:FLJ34254, FLJ35396, FLJ37216, FLJ54658, IGLON3, LAMP
Protein Construction:A DNA sequence encoding the human LSAMP (Q13449) (Met 1-Asn 315), without the pro peptide, was expressed, with a polyhistidine tag at the C-terminus.
Expressed Host:Human Cells
Form & Shipping:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
LSAMPProtein QC Testing
Purity:> 97 % as determined by SDS-PAGE
Endotoxin:< 1.0 EU per μg of the protein as determined by the LAL method
Stability:Samples are stable for up to twelve months from date of receipt at -70℃
Predicted N Terminal:Val 29
Molecule Mass:The secreted mature form of recombinant human LSAMP consists of 298 amino acids and has a predicted molecular mass of 33.4 kDa. As a result of glycosylation, the apparent molecular mass of rhLSAMP is approximately 45-55 kDa in SDS-PAGE under reducing conditions.
Formulation:Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
LSAMPProtein Usage Guide
Storage:Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution:A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

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 have been found that rats with increased level of anxiety had 1.6-fold higher expression of LsAMP gene in the periaqueductal gray compared to rats with low level of anxiety, indicating a possible role of LsAMP in the regulation of anxiety.
