Alternative names:

Tp44

Description:

Recombinant human CD28 Protein with C-terminal 10×His tag

Background:

The protein encoded by this gene is essential for T-cell proliferation and survival, cytokine production, and T-helper type-2 development. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jul 2011]

Molecular characterization:

CD28(Asn19-Pro152) 10×His tag

Molecular weight:

The protein has a predicted molecular mass of 16.5 kDa after removal of the signal peptide.

Tag:

C-10×His tag

Expression host:

HEK293

Target:

CD28

Purity:

The purity of the protein is greater than 85% as determined by SDS-PAGE and Coomassie blue staining.

Formulation / Reconstitution:

Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8% trehalose is added as protectants before lyophilization. Please see Certificate of Analysis for specific instructions.

Storage:

Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (Avoid repeated freezing and thawing). Lyophilized proteins are shipped at ambient temperature.
