Kell Antigen Expression Analysis

For detection of K1 expression, splenocytes, peripheral blood, and platelet-rich plasma were stained with a monoclonal anti-Kell Ab (Mima-8) (58 (link)) followed by anti-mouse IgG and Abs against cell type—specific markers. Mima-8 recognizes the Jsb epitope on the human Kell glycoprotein, which is expressed by the K1 transgene. A combination of Mima-8 and Mima-9, which recognizes Kpb epitopes of the K1 transgene, was used to compare K1 expression by KEL1A and K1 mice. Platelet-rich plasma was generated by centrifuging peripheral blood at 8000 × g for 10 min. For analysis of dendritic cells (DCs), spleens were minced with a razor blade and filtered through 100 μm Nylon mesh prior to RBC lysis. Single-cell suspensions were stained with fluorescently conjugated Abs specific for cell-surface proteins, including CD19 (Clone: 6D5), TCRβ (H57-597), and I-A/I-E [MHC class II (MHCII), M5/114.15.2], CD86 (GL-1), Ly6C (HK1.4) and F4/80 (BM8) from BioLegend (San Diego, CA); CD45.1 (A20), CD11c (N418), CD11b (M1/70), CD8α (53-6.7), Ter-119, and Siglec H (eBio440c) from eBioscience (San Diego, CA), and CD41 (MWReg30) from BD Biosciences (San Jose, CA). Zombie-NIR (BioLegend) was used to exclude dead cells. Cells were acquired with a Miltenyi MACSQuant flow cytometer and analyzed using FlowJo.

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.
