MHC specific antibody was covalently conjugated to N-hydroxysuccinamide magnetic beads (Pierce) per manufacturer’s protocol. 50 to 100 ug protein equivalent of EVs were incubated with antibody beads overnight at 4°C. The bead bound EV fractions were separated per manufacturer’s protocol. EVs bound to beads were eluted using tris glycine and utilized for downstream analysis. Unconjugated HLA allele-specific anti-HLA A2 monoclonal IgG antibody (Catalogue # 0791HA) was purchased from One Lambda (West Hills, CA, USA), for donor HLA class I specific exosome isolation from recipient mouse plasma total pool of exosomes. Antibodies to insulin (15848–1-AP; used at a dilution of 1:200), TSG 101(28283–1-AP; used at a dilution of 1:500) were purchased from Proteintech Lab; antibodies to GLP1R (sc-390774; used at a dilution of 1:200), GLP-1(sc-57166; used at a dilution of 1:200), Bcl-2 (sc-7382; used at a dilution of 1:200), and Bcl-XL (sc-56021; used at a dilution of 1:200) were purchased from Santa Cruz Biotechnologies, Inc. Secondary antibodies conjugated to HRP (ready-to-use anti-rabbit, anti-mouse were purchased from Vector Lab: MP7451 and MP7452, respectively).

Serial FFPE sections (4 um) were deparaffinized in xylene and then rehy- drated in 100%, 90% and 70% alcohol successively. Antigen unmasking was performed with a preheated epitope retrieval solution (100X citrate buffer, pH 6.0), and endogenous peroxidase was inactivated by incubation in 3% H2O2 for 20 mins. Next, the sections were preincubated with 10% normal goat serum and then incubated overnight with the following primary antibodies: anti-ELOVL2 antibody (1:50, 20308-1-AP, Proteintech); anti-CD3 antibody (1:100, ab16669, Abcam); anti-CD8 antibody (1:100, ab17147, Abcam). Next, sections were incubated with the corresponding horseradish peroxidase (HRP)-conjugated secondary antibodies (ready-to-use, MP-7451 and MP-7452, VectorLab) for 30 mins at room temperature and and development with DAB substrate (Vector Laboratories). Sections were counterstained with hematoxylin. Slides were scanned using PANNORAMIC Digital Slide Scanners, and QuPath software was used to quantify positive staining cells.

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.
