Product Description |
Recombinant Human CD72 Protein is expressed from HEK293 with His tag at the N-Terminus.It contains Arg117-Asp359. |
Product Background |
CD72 (originally Lyb-2), a 45 kDa type II transmembrane glycoprotein. CD72 belongs to the calcium-dependent C-type lectin superfamily and shares sequence homology with CD23 (the B-cell-specific low-affinity Fc receptor for IgE) and the asialoglycoprotein receptors. It is expressed as a disulfide-linked homodimer from the pro-B through the mature B-cell stage, but it is downregulated on terminally differentiated plasma cells. |

N-His |
Express System |
HEK293 |
Purity |
> 95% as determined by Bis-Tris PAGE |
Endotoxin |
Less than 1EU per ug by the LAL method. |
Form |
Lyophilized |
Shipping |
Shipped at ambient temperature. |
Formulation |
Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water. |
Stability And Storage |
Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. |
