From: Optimizing Human Synovial Fluid Preparation for Two-Dimensional Gel Electrophoresis

SF Sample Treatment Method (n = 3) Number of Protein Spots
Untreated 456 ± 33
Acetone Precipitation 320 ± 28+#
2-D Clean-Up Kit 413 ± 31
Acetone and 2-D Clean-Up Kit 278 ± 26*
  1. Comparison between acetone precipitation method and untreated SF sample: + = p < 0.05.
  2. Comparison between acetone precipitation method and 2-D Clean-Up Kit: # = p < 0.05.
  3. Comparison between combined acetone/2-D Clean-Up Kit treated SF sample, and untreated
  4. SF sample, and SF sample treated with acetone precipitation method: * = p < 0.05.
  5. Values expressed as mean ± standard error of means (SEM).
