Long descriptionAnti-human CD28 binds the 44kDa MW cell surface protein on the surface of most T cells. CD28 acts as the ligand for the B7/BB-1 molecule on the surface of activated B cells. B7/BB-1 costimulates T cells through CD28, along with CD2 and CD3.CD28 antigen is a disulfide-linked homodimeric glycoprotein. The CD28 antigen is present on approximately 60%-80% T lymphocytes (95% of CD4 and 50% of CD8 lymphocytes). CD28 regulates the expression of cytokines by T cells, not only IL-2, but also IL-1 alpha and CSF-1, usually synthesized by accessory cells. CD28 functions as a cell adhesion molecule (CAM) for certain T cell subsets.
Antibody come fromCD28=Derived from the hybridization of mouse Sp2/O-Ag14 myeloma cells with spleen cells of BALB/c mice immunized with the HPB-ALL T-cell line.

ApplicationFlow Cytometry
Antibody's suited forPBMC: Add10 µl of MAB/10^6 PBMC in 100 µl PBS. Mix gently and incubate for 15 minutes at 2¼ to 8¼C. Wash twice with PBS and analyze or fix with 0.5% v/v of paraformaldehyde in PBS and analyze. WHOLE BLOOD: Add 10 µl of MAB/100 µl of whole blood. Mix gently and incubate for 15 minutes at room temperature (20¼C). Lyse the whole blood. Wash once with PBS and analyze or fix with 0.5% v/v of paraformaldehyde in PBS and analyze. See instrument manufacturerÕs instructions for Lysed Whole Blood and Immunofluorescence analysis with a flow cytometer or microscope.
Storage-20ºC

WarningsThis product is intended FOR RESEARCH USE ONLY, and FOR TESTS IN VITRO, not for use in diagnostic or therapeutic procedures involving humans or animals. This datasheet is as accurate as reasonably achievable, but Nordic-MUbio accepts no liability for any inaccuracies or omissions in this information.
DescriptionThis antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided.
TestMouse or mice from the Mus musculus species are used for production of mouse monoclonal antibodies or mabs and as research model for humans in your lab. Mouse are mature after 40 days for females and 55 days for males. The female mice are pregnant only 20 days and can give birth to 10 litters of 6-8 mice a year. Transgenic, knock-out, congenic and inbread strains are known for C57BL/6, A/J, BALB/c, SCID while the CD-1 is outbred as strain.
