Description
Accession
P06729
Source
DNA sequence encoding Human CD2/SRBC including a C-His tag was expressed in HEK293 Cells.
Molecular weight
Recombinant Human CD2/SRBC is a protein consisting of amino acid residues [Lys25-Asp209] ,The protein has a predicted MW of 22.3 kDa. Due to glycosylation, the protein migrates to 40-50 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 CD2/SRBC 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
