[49] Reaction of proteins with citraconic anhydride.
M Z Atassi et al.
Methods in enzymology, 25, 546-553 (1972-01-01)
P P Batra
The International journal of biochemistry, 23(12), 1375-1384 (1991-01-01)
The lysine residues were modified to varying degrees (50-91%) with citraconic anhydride to determine the extent of conformational change in ovalbumin. Major findings included: 1. Sixteen of the 20 lysine residues are located on the protein surface, while the remaining
Anthony S-Y Leong et al.
Pathology, 42(1), 77-81 (2009-12-23)
The introduction of heat-induced antigen retrieval has been a major milestone in diagnostic immunohistochemistry, enabling the application of many antibodies to fixed paraffin-embedded tissue sections. A number of important variables affect the preservation of tissue antigens, among which are analytical

Protein engineering, design & selection : PEDS, 19(4), 169-173 (2006-02-03)
Horseradish peroxidase (HRP) was modified by maleic anhydride and citraconic anhydride. The thermal and organic solvent tolerances of native and modified enzyme were compared. These chemical modifications of HRP increased their thermostability both in aqueous buffer and some organic solvents
J K Shetty et al.
The Biochemical journal, 191(1), 269-272 (1980-10-01)
Modification of proteins with citraconic anhydride altered the electrostatic relationship between cationic epsilon-NH3+ groups of lysine residues of proteins and anionic phosphate groups of nucleic acids, thereby destabilizing the nucleoprotein complex. This procedure facilitated the separation of proteins from nucleic
