M T Wilson et al.
European journal of biochemistry, 77(1), 193-199 (1977-07-01)
The ferric form of the haem undecapeptide, derived from horse cytochrome c by peptic digestion, undergoes at least three pH-induced transitions with pK values of 3.4, 5.8 and 7.6. Temperature-jump experiments suggest that the first of these is due to
N Ghinea
Analytical biochemistry, 155(1), 78-82 (1986-05-15)
A rapid and sensitive method has been developed for detecting glycosaminoglycans on cellulose acetate strips. The method is based on the electrostatic interactions between glycosaminoglycans and cationic heme undecapeptide. The complexes are identified by peroxidatic reaction using 3,3'-diaminobenzidine as H2
