Abstract
Background
Knowing how the protein profile of platelet products changes with storage or leuko-reduction may give us greater insight into cell physiology and the cause of transfusion reactions other than cytokines and chemokines.
Methods
We filtered four packs of platelet concentrates (PC) within 24 hr of blood collection and after 120 hrs of storage. Four aliquots of each supernatant in PC were obtained: pre-storage+pre-filtration, pre-storage+post-filtration, post-storage+pre-filtration and post-storage+post-filtration. Routine chemistry tests and a two-dimensional electrophoresis (2-DE) were performed. The stained images were analyzed and the significant spots were identified using a peptide mass finger printing (PMF) with matrix assisted laser desorption/ionization-time of flight (MALDI-TOF) analysis after trypsin digestion.
Results
The protein spots increased with storage and decreased after filtration (P<0.05, pre-storage+post-filtration). The spot density of various proteins, including macrophage inflammatory protein-2 alpha, megakaryocyte colony stimulating factor and interleukin-22 changed with storage and leukoreduction.
