| Product Name | Recombinant Human CD28 Protein >90% Purity HEK293 Expressed 1 mg |
| Catalog No. | AATM-HMM-0035 |
| Description | This recombinant human CD28 protein is expressed in HEK293 mammalian cells and supplied as a purified solution. CD28 is a critical costimulatory receptor on T cells that provides essential signals for T cell activation and proliferation. The protein has an apparent molecular weight of 55-72 kDa as determined by SDS-PAGE, with a purity exceeding 90%. It is supplied at a concentration of 1-2 mg/ml formulated in 1×PBS at pH 7.4, packaged in 1 mg aliquots. This product is suitable for research applications investigating T cell biology, immune checkpoint pathways, and related protein studies. |
| Intended Use | For research use only in T cell costimulation studies, immune checkpoint research, and protein interaction investigations. Not for use in human experiments. |
