Overview

ImmunoCult™-ACF Human B Cell Expansion Supplement is a serum-free and animal component-free supplement formulated to promote robust in vitro expansion of human peripheral blood B cells in the absence of serum, feeder cells, or specialized culture plates. The supplement contains recombinant proteins and chemically defined components that support the activation and expansion of human B cells and their maturation to plasma cells.

ImmunoCult™-ACF Human B Cell Expansion Supplement is a 50X supplement that can be added to a base medium such as ImmunoCult™-XF T Cell Expansion Medium (Catalog #10981) to prepare a complete serum-free medium for culturing and expanding human B cells.

Fold expansion and maturation of B cells cultured with ImmunoCult™-ACF Human B Cell Expansion Supplement

Figure 1. Expansion and Maturation of Human B Cells with ImmunoCult™-ACF Human B Cell Expansion Supplement

B cells isolated from human PBMCs (leukapheresis packs) using EasySep™ Human Pan-B Cell Enrichment Kit were seeded at 1 x 10^5 cells/well in 24-well tissue culture plates with ImmunoCult™-ACF Human B Cell Expansion Supplement. ImmunoCult™-XF T Cell Expansion Medium was used as a base medium. The cells were passaged every 3 - 4 days. (A) Fold expansion of viable cells is shown for n = 12 donors, with bars representing the mean and 95% confidence level (range 38- to 1,190-fold at day 14 ± 1 day). (B) Expression of CD138 and CD20 was analyzed by flow cytometry at each timepoint (data represent % positive viable cells; mean ± 1 SD). The observed changes indicate maturation of B cells to plasma cells/blasts.

Figure 2. Light Microscopy Image of Cultured Human B Cells

B cells isolated from human PBMCs (Leukopak) using EasySep™ Human Pan-B Cell Enrichment Kit were seeded at 1 x 10^5 cells/well in a 24-well tissue culture plate with ImmunoCult™-ACF Human B Cell Expansion Supplement. ImmunoCult™-XF T Cell Expansion Medium was used as a base medium. The cells were passaged on day 4 after seeding and imaged at 40x magnification on day 6.

Figure 3. Expansion and Viability of Human Memory B Cells Cultured with ImmunoCult™-ACF Human B Cell Expansion Supplement

Memory B cells were isolated from human PBMCs (Leukopak) using EasySep™ Human Memory B Cell Isolation Kit and were seeded at 0.5 x 10^5 cells/well in 48-well tissue culture plates with ImmunoCult™-ACF Human B Cell Expansion Supplement. ImmunoCult™-XF T Cell Expansion Medium was used as a base medium. The cells were passaged every 2 - 4 days and the fold expansion of viable cells (A) and cell viability (B) were calculated at each time point. Data represent the mean ± 1 SD of triplicate cultures for the same donor.

Figure 4. Expansion and Viability of Human Naive B Cells Cultured with ImmunoCult™-ACF Human B Cell Expansion Supplement

Naive B cells were isolated from human PBMCs (Leukopak) using EasySep™ Human Memory B Cell Isolation Kit and were seeded at 0.5 x 10^5 cells/well in 48-well tissue culture plates with ImmunoCult™-ACF Human B Cell Expansion Supplement. ImmunoCult™-XF T Cell Expansion Medium was used as a base medium. The cells were passaged every 2 - 4 days and the fold expansion of viable cells (A) and cell viability (B) were calculated at each time point. Data represent the mean ± 1 SD of triplicate cultures for the same donor.
