Cd8 sk1 or rpa t8

Manufactured by BioLegend

CD8 (SK1 or RPA-T8) is a laboratory reagent used to detect and identify CD8+ T cells. It is a monoclonal antibody that specifically binds to the CD8 surface antigen, which is expressed on the surface of cytotoxic T cells and a subset of natural killer cells. This reagent can be used in various immunological assays, such as flow cytometry, to quantify and characterize CD8+ T cell populations.

Single-cell suspensions were washed with PBS and stained with LIVE/DEAD Fixable Dead Cell Stain (Thermo Fisher) for 15 minutes, followed by staining with an optimized antibody cocktail for 20 minutes at room temperature (RT). Cells were then washed with FACS buffer (PBS containing 2% FBS) and fixed in PBS containing 1% paraformaldehyde (Sigma-Aldrich). For samples requiring intracellular staining, cells were processed using the Foxp3/Transcription Factor Staining Buffer Set (Thermo Fisher) according to the manufacture’s instruction. Samples were acquired using a FACSymphony (BD Biosciences). Data were analyzed with FlowJo software (version 9.8.8 or higher, BD Biosciences). All sorting experiments were carried out on freshly isolated cells using a FACSAriaII (BD Biosciences). Antibodies used include: CD45 (HI30), CD103 (Ber-ACT8), CD45RA (HI100, Biolegend), CD3 (UCHT1), CD69 (FN50), CD8 (SK1 or RPA-T8), CCR7 (G043H7, Biolegend), CD25 (M-A251), CD127 (HIL-7R-M21), CD4 (RPA-T4), CCR5 (2D7), PD-1 (EH12.1, Biolegend), Granzyme B (GB11), Foxp3 (259D/C7), CTLA4 (BNI3), IL-17A (N49-653), IL-2 (5344.111), (TNFα (Mab11), IFNγ (B27). All antibodies were from BD Biosciences unless otherwise noted.

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.
