The gravitational split-flow thin channel (G-SPLITT) system effectively sorts myeloma cells from healthy splenocytes. This innovative technique uses sedimentation differences for rapid, precise biomaterial fractionation.

Area of Science:

  • Biotechnology
  • Cell Separation
  • Biomaterial Fractionation

Background:

  • Innovative separation techniques are crucial for biomaterial fractionation.
  • Existing methods may lack efficiency or precision for complex cell mixtures.

Purpose of the Study:

  • To evaluate the gravitational split-flow thin channel (G-SPLITT) system as a cell sorter.
  • To demonstrate rapid separation of myeloma cells from splenocytes.

Main Methods:

  • Utilized the G-SPLITT system for cell separation.
  • Employed cell tracking velocimetry to measure sedimentation rates directly.
  • Calculated optimal flow conditions based on theoretical mathematical descriptions.

Main Results:
