Alkaline haematin and nitrogenous ligands

The kinetics of the recombination reaction between apomyoglobin and alkaline haematin.

Apomyoglobin was prepared by an extremely mild modification of the acid/butanone technique, and the kinetics of the recombination reaction between this preparation and alkaline haematin were studied. The recombination has been shown to be precisely second-order and mono-phasic. Rate constants obtained from the study are in good agreement with values obtained previously by an indirect technique ...

Evaluation of the alkaline haematin D-575 method for haemoglobin estimation in east

In many health facilities in east Africa, haemoglobin estimation is performed using visual colour comparison methods. Efforts to establish colorimetric methods face numerous constraints, including the unavailability of standards for quality control. In contrast, the alkaline haematin D-575 method for haemoglobin estimation is a colorimetric method that uses primary standards prepared from pure,...

Observations on the alkaline haematin/detergent complex proposed for measuring haemoglobin concentration.

The "alkaline haematin D-575" method for determining haemoglobin, described by Zander et al. [1984) Clin. Chim. Acta 136, 83-93) was tested. Claims that different non-ionic detergents in the reagent result in identical values for the haemoglobin concentration being measured could not be verified. It could also not be verified that a stable end-product with unique spectral characteristics is alw...
