In this video, we demonstrate the isolation of B cells from human peripheral blood using biotinylated antibodies specific for non-B cells and streptavidin-conjugated magnetic microbeads.
Protocol
All procedures involving human participants have been performed in compliance with the institutional, national, and international guidelines for human welfare and have been reviewed by the local institutional review board 1. Isolation and Purification of Human Peripheral Blood B Cells Draw ~ 10 mL of blood from the median cubital vein (in the cubital fossa anterior to the elbow) into a 15-mL tube containing K2EDTA (1.5 to 2.0 mg/mL blood) and immediately…
