Immune cell isolation directly from buffy coat

StraightFrom® Buffy Coat MicroBeads allow for the magnetic cell isolation directly from buffy coat. Leukocyte subsets such as CD4⁺, CD8⁺, CD14⁺, CD19⁺,or CD56⁺ cells can be purified using either MultiMACS™ Instruments or manual separators. Pre-enrichment of white blood cells, e.g. by density gradient centrifugation, is not required. The purified cells are well-suited for further flow cytometric analyses, molecular biology applications, and functional studies.

Buffy coat as starting material

As by-products from whole blood donations, buffy coats contain the same amount of leukocytes as the original blood donation, but in higher concentrations. Buffy coats are ideally suited for enrichment of high amounts of leukocyte subset from PBMCs.

Manual cell separation

Manual isolation of pure cells directly from an entire buffy coat.

With StraightFrom Buffy Coat MicroBead Kits, an entire buffy coat can be processed into target cells in less than 30 minutes.

Together with Whole Blood Columns (included in the kit) and magnetic separators such as the QuadroMACS™ Separator, leukocytes can be manually enriched. First, the MicroBeads are added directly to the blood sample without any prior cell counting or PBMC isolation. Leukocytes can then be isolated straightforward within minutes without the need for density gradient centrifugation.

Automated cell isolation with the MultiMACS Cell24 Separator Plus

Semi-automated cell isolation directly from buffy coat with the MultiMACS™ Cell24 Separator Plus.

View details

The MultiMACS Cell24 Separator Plus is ideally suited to process an entire buffy coat in a single run with StraightFrom Buffy Coat MicroBeads. The 30-minute isolation procedure results in cell populations with high purities and recovery rates. With 12 Whole Blood Columns (included in the kit), the instrument allows for time saving cell isolation when processing large sample volumes, while providing reliability and reproducibility in day-to-day cell separations.

For large-scale cell separations, the MultiMACS X is the instrument of choice.

Separation of a buffy coat sample using the StraightFrom^®Buffy Coat CD4 MicroBead Kit and the MultiMACS™ Cell24 Separator Plus with the Single-Column Adapter and Whole Blood Columns. Cells were fluorescently stained with CD4-PE, CD14-APC, as well as CD45-VioBlue^®and analyzed by flow cytometry using the MACSQuant® Analyzer. Cells were triggered via CD45-VioBlue, cell debris, and dead cells were excluded from the analysis based on scatter signals and propidium iodide fluorescence.
