CD58 Protein, Human, Recombinant (hFc Tag)

CD53 is a member of the transmembrane 4 superfamily, also called the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. These proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. CD53 is a cell surface glycoprotein that is known to complex with integrins. Familial deficiency of CD53 gene has been linked to an immunodeficiency associated with recurrent infectious diseases caused by bacteria, fungi and viruses. CD53 contributes to the transduction of CD2-generated signals in T cells and natural killer cells and has been suggested to play a role in growth regulation.

1. Measured by its binding ability in a functional ELISA. Immobilized human CD2-His (Cat:PH50663M2) at 10 μg/ml (100 μl/well) can bind human CD58-Fc, The ECof human CD58-Fc is 0.04-0.1 μg/ml. 2. Measured by its binding ability in a functional ELISA. Immobilized Cynomolgus CD2-His (Cat:PK54088M2) at 10 μg/ml (100 μl/well) can bind human CD58-Fc, The ECof human CD58-Fc is 0.04-0.10 μg/ml.

Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

The recombinant human CD58/Fc is a disulfide-linked homodimer. The reduced monomer comprises 428 amino acids and has a predicted molecular mass of 48.5 kDa. The apparent molecular mass of the protein is approximately 68 kDa in SDS-PAGE under reducing conditions.

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. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
