Step By Step Isolation of B Cells

My sister just started for a new employer. She used to work in a diagnostic lab which determines diseases. It's more like a pathology laboratory. She's used to tissue analysis especially for biopsy. This new lab specializes on stem cell research. She has been assigned to cell isolation. Being new to this procedure, a media kit which shows the step by step  isolation of b cells was at hand for her use. She quickly grasped the procedure and could now do it on her own. Her boss is so impressed that she received a raise despite working for the lab for just a month.
