|
LC-MS/MS
|
- Findings show fibrin proteins were the most abundant components followed by albumin
- Substrates of FXIIIa were identified: PAI-1, THBS1, and FINC
- Cellular components (hemoglobin and integrins) interact with fibrin clot
- Majority of cross-links originated from α c region of fibrinogen-α
- C-terminal y–y peptide cross-linking was determined to be higher in the in vivo thrombus compared with the whole-blood clot

LC- MS/MS
|
- 494 proteins identified in the plasma fibrin clot
- Highest protein concentrations found in clot were three fibrinogen chains (64%) and fibronectin (13%)
- Protein concentrations less than 0.1% were antithrombin, platelet factor 4 and factor V, vWF, and others.
- Fibrinogen-a and -y chains were associated with age
- BMI was associated with clot bound apolipoproteins
- Clot lysis time correlated with age, fibrinogen-a and -y, and histidine-rich glycoprotein
- HRG may modulate plasmin-mediated clot lysis
- C-reactive protein was detected in most plasma clots
