Phosphorylated proteins in the CAR-T cells were analyzed by intracellular flow cytometry following coculture with NALM-6 or K562 at an E:T ratio of 1:1. The cells were fixed with 1.6 % formaldehyde, followed by permeabilization by ice-cold methanol. The following antibodies were used: Alexa Fluor 647-anti-phospho-STAT3 (Tyr705) (clone 4/P-Stat3, BD Biosciences), Alexa Fluor 647-anti-phospho-STAT5 (Tyr694) (clone 47/Stat5, BD Biosciences), Alexa Fluor 647-anti-phospho-p44/42 MAPK (Erk1/2) (Thr202/Tyr204) (clone 20A, BD Biosciences), and anti-phospho-Akt (Thr308) (clone D25E6, Cell Signaling Technology). Alexa Fluor 647-anti-rabbit IgG (H+L) (Jackson ImmunoResearch) was used as the secondary antibody following the staining with the anti–phospho-Akt antibody. The STAT3 inhibitor S3I-201 (Selleck Chemicals) and the STAT5 inhibitor pimozide (Cayman Chemical) were used at concentrations of 25 μM and 5 μM, respectively.

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.
