Description
Accession
P18627
Source
DNA sequence encoding Human LAG3/CD223 including a C-His tag was expressed in HEK293 Cells.
Molecular weight
Recombinant Human LAG3/CD223 is a protein consisting of amino acid residues [Leu23-Gly434] ,The protein has a predicted MW of 45.5 kDa. Due to glycosylation, the protein migrates to 55-65 kDa based on Tris-Bis PAGE result..
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
see methods section
Endotoxin
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
Presentation
Recombinant Human LAG3/CD223 was lyophilized from 0.2 µm filtered PBS solution pH7.4
Reconstitution
Centrifuge vial to ensure maximal product extraction, recommended:20sec, 5K RPM
Storage
The lyophilized protein is stable for at least 2 years from date of receipt at -20° C.
Usage
This product is for research purposes only.It may not be used for therapeutics or diagnostic purposes.
