- ITIH4 has been isolated from acute phase dog sera in a single step.
- Specific antibodies against the isolated proteins have been developed.
- Canine acute phase response was studied in two different kinds of major surgeries.
- ITIH4 and CRP concentrations increased significantly after surgical trauma.
- Canine ITIH4 can be considered a new positive acute phase protein.
Inter-α-trypsin inhibitor heavy chain 4 (ITIH4) and C-reactive protein (CRP) have been isolated from acute phase dog sera by affinity chromatography with insolubilized polyclonal antibodies anti pig Major Acute phase Protein (Pig-MAP) and with p-Aminophenyl Phosphoryl Choline, respectively. Isolated proteins were used to prepare specific polyclonal rabbit antisera that have allowed quantifying their concentration in serum samples by single radial immunodifussion. Both proteins were quantified in sera from female dogs that had undergone ovariohysterectomy (OVH, n = 9) or mastectomy (n = 10). The observed increases in CRP concentrations showed that surgical traumas induced an acute phase response of a great magnitude in the dogs. In both surgeries a four-fold increase of ITIH4 concentrations was detected. It can be concluded that ITIH4 is a new positive acute phase protein in dogs, as reported in other species.
