Single-cell suspensions were resuspended in PBS 2% FCS and stained for flow cytometric analysis. Data were acquired with a LSR Fortessa (BD Biosciences) and analyzed using FlowJo software. Antibodies against the following molecules were used: CD19 (6D5), CD93 (AA4.1), CD23 (B3B4), CD1d (1B1), GL7 (GL-7), β1-integrin (HMb1-1), β2-integrin (M18/2), VCAM-1 (429), anti-rat PE to detect VCAM-1, and IgG2a isotype control were from eBioscience; CD21 (7G6), B220 (RA3-6B2), CD138 (281-2), CD5 (53-7.3), IgM (R6-60.2), Igλ (R26-46), Fas (Jo2), Gr1 (RB6-8C5), and α4-integrin (9C10) from BD. αL-integrin (M17/4) and CD11b (M1/70) were from BioLegend. NP hapten conjugated to PE was from Biosearch Technologies. For detecting intracellular phosphorylated proteins, cells were stained for 20 min with surface markers and then cells were fixed and permeabilized with Cytofix/Cytoperm solution according to the protocol’s instructions (catalog No. 554723; BD Biosciences). Cells were incubated overnight (ON) with the unconjugated rabbit anti-mouse p-Syk (C87C1; Cell Signaling Technology) and rabbit anti-mouse p-Lyn (Cell Signaling Technology) followed by AF488 or AF647-conjugated anti-rabbit secondary antibody. Anti-CD16/32 (93; BD) was used to block nonspecific binding.

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.
