Idelalisib (CAL-101, GS-1101; PI3Kδ inhibitor), duvelisib (IPI-145, INK1197; PI3Kγδ dual inhibitor), AS-604850 (PI3Kγ inhibitor) and ibrutinib (BTK inhibitor) were purchased from Selleckchem (Houston, TX) and all used at 1 μM concentration in most experiments. In some experiments inhibitors were used at 0.1 μM or 0.5 μM concentrations, as specifically indicated in the corresponding figure legend.

Chemotaxis Assay for Cell Migration

Check if the same lab product or an alternative is used in the 5 most similar protocols
CCL21 and CXCL12 were from Peprotech, and CXCL13 was purchased from R&D systems. Chemotaxis assays were carried out using Transwell chambers (5 µm pore size; CoStar) adding 100 µl cell suspension (5 x 106 cells/ml) in complete medium (RPMI/10% FCS/standard supplements) to the top chamber and indicated amounts of chemokine in the bottom chamber. After 2 h at 37°C, 7% CO2, the percentage of migrated cells was calculated by flow cytometry after comparing with a precalibrated bead standard (Sigma-Aldrich) and correcting for variations in input concentrations. The DOCK2 inhibitor CPYPP (Selleck) was used at 40 µM throughout the chemotaxis assay (15 (link)). The isoform-specific PI3K inhibitors TGX221 (0.1 µM final conc.; Tocris), PI-103 (1 µM; Tocris), AS604850 (1 µM; Selleck),and IC-87114 (0.5 µM; Selleck) were present throughout the chemotaxis assay.

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.
