Specifications
| 10µg / 50µg / 100µg |
Alternative names:
CD28;Tp44
Description:
Recombinant human CD28 protein with C-terminal mouse Fc and 6×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.
Molecular characterization:
CD28(Asn19-Pro152) mFc(Pro99-Lys330) 6×His
Molecular weight:
The protein has a predicted molecular mass of 68-72 kDa after removal of the signal peptide.
Tag:
C-Mouse Fc and 6×His Tag
Expression host:
HEK293
Target:
CD28
Purity:
The purity of the protein is greater than 95% 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 of reconstitution.
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.
