Product details
References
Isotype
Mouse IgG1 kappa
Specificity
The mouse monoclonal antibody JJ319 reacts with an extracellular epitope of CD28, a disulfide-linked homodimeric type I glycoprotein (monomer of Mw 44 kDa) which is a critical costimulatory receptor of T cells.
Application
IP, FC (QC tested), FUNC
Application details
Flow cytometry: Recommended dilution: 3-12 µg/ml
Reactivity
Rat
Immunogen
Mouse A20J B lymphoma cells transfected with rat CD28
Other names
Tp44
Concentration
1 mg/ml
Preparation
Purified by protein-A affinity chromatography
Formulation
Low endotoxin azide free phosphate buffered saline (PBS) solution, 0.2 μm filter sterilized. Endotoxin level is less than 0.01 EU/μg of the protein, as determined by the LAL test.
