On days 3 to 8, two-thirds of the culture media were replaced with fresh BCM every day. On day 9, culture supernatants were harvested for ELISA determinations and culture plates were stored at −80°C for V(D)J amplifications.

All culture supernatants from single-cell cultured memory B cells used in this study were generated and reported as part as a previous study (see Sokal et al., 2021b (link)). Briefly, single B cells were sorted in 96-well plates containing MS40Llo cells expressing CD40L (kind gift from G. Kelsoe, Crickx et al., 2021 (link); Luo et al., 2009 (link)).

Part of the supernatant was carefully removed at days 4, 8, 12, 15 and 18 and the same amount of fresh medium with cytokines was added to the cultures. After 21 days of single cell culture, supernatants were harvested and stored at -20°C. Cell pellets were placed on ice and gently washed with PBS (Gibco) before being resuspended in 50 μL of RLT buffer (Qiagen) supplemented with 1% 2-mercaptoethanol and subsequently stored at -80°C until further processing.

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.
