Anti human cd28 clone 28.6 mab

Manufactured by Thermo Fisher Scientific

The Anti-human CD28 (clone 28.6) mAb is a monoclonal antibody that binds to the CD28 receptor on human cells. The CD28 receptor is a co-stimulatory molecule that plays a crucial role in the activation and proliferation of T cells. This antibody can be used in various immunological applications such as flow cytometry, immunoprecipitation, and cell stimulation experiments.

Human peripheral blood mononuclear cells (PBMC) were isolated from the blood of adult donors obtained from the Blood Transfusion Centre (University Medical Center Freiburg). Venous blood was centrifuged on a LymphoPrep™ gradient (density: 1.077 g/cm3, 20 min, 500g, 20 °C; Progen). Afterwards cells were washed three times with PBS and cell viability and concentration was determined using the trypan blue exclusion test. Cells were cultured in Roswell Park Memorial Institute (RPMI) 1640 medium (Invitrogen) supplemented with 10% heat-inactivated fetal bovine serum (PAA), 2 mM L-glutamine, 100 U/mL penicillin and 100 U/mL streptomycin (Invitrogen) at 37 °C in a humidified incubator with a 5% CO2/95% air atmosphere. PBMC were additionally stimulated with anti-human CD3 (clone HIT3) and anti-human CD28 (clone 28.6) mAb (100 ng/mL; both from eBioscience). Incubation was carried out as indicated in the figure captions in the presence of medium alone, different control substances, C. ipecacuanha fractions, or isolated cyclotides.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
