Formulation
Lyophilized from sterile Phosphate Buffered Saline, pH 7.4. Normally 5%–8% Trehalose is added as a protectant before lyophilization.
Stockage
Shipped at 4°C. Lyophilized: Store at -20°C to -80°C. Reconstituted: Aliquot and store at -80°C. Product is stable for one year. Avoid freeze/thaw cycles.
Notes générales
Prior to reconstitution, centrifuge the vial at 5,000g for 3-5 minutes at room temperature. Reconstitute with appropriate volume of distilled sterile water to bring product to 1mg/ml concentration. After addition of distilled sterile water, mix by gentle tapping. Note: It is not recommended to vortex or vigorously pipette the sample.

ELISA plates were pre-coated with Recombinant Human CD28 Protein (Fc Chimera 6xHis Tag) (A318394) at 2 µg/ml (100 µl/well) which can bind Anti-CD28 Antibody [DM63] - BSA and Azide free (A318634) in a linear range of 1-100 ng/ml.
Expi 293 cell line was transfected with irrelevant protein (A) and human CD28 (B) were surface stained with Anti-CD28 Antibody [DM63] - BSA and Azide free (A318634) at 1µg/ml followed by Anti-Rabbit IgG Antibody (Alexa 488).

Flow cytometry analysis of antigen binding of Anti-CD28 Antibody [DM63] - BSA and Azide free (A318634). (A) Anti-CD28 Antibody [DM63] - BSA and Azide free (A318634) does not bind to 293T cells that do not express CD28. (B) A clear peak shift of Anti-CD28 Antibody [DM63] - BSA and Azide free (A318634) was seen compared to the control when incubated with CD28-expressing Jurkat cells, indicating strong binding of Anti-CD28 Antibody [DM63] - BSA and Azide free (A318634) to CD28. Antibodies were incubated at 2 µg/ml. .
