OBJECTIVE: To compare and contrast the characteristics of suicides among aboriginal and
nonaboriginal people in Manitoba. DESIGN: Retrospective review of all suicides, based on a …

The reactivity of the five main histones in calf thymus chromatin towards acetic anhydride has
been determined using the technique of competitive labelling (Kaplan et al., 1971; Kaplan, …

A disulfide of haptoglobin 1-1 has been selectively cleaved using sodium sulfite and p-chloro-mercurisulfonate.
The reaction product (half-haptoglobin) could be separated from …

Cyanogen bromide cleavages have been performed on the three major haptoglobin types
in order to study the interchain disulfide linkages. Fragments (PC III's) were isolated which …

Human haptoglobin (Hp) combines with hemoglobin double molecules (Hb∙Hb) isolated from
an inbred strain of mice, DBA/2J. When low ionic strength solutions of the two proteins are …

… The initial amino acid composition and the strong evidence that the a and ,B chains could
sequence analysis of the a chain of human hap not be separated unless disulfide bonds were …

… We have previously shown (Malchy & Kaplan, 1974) that the N-terminal proline residue of
histone IIb2 is responsible for most of the observed reactivity and, as in the case of the other …

The rate of reaction of the β93 sulfhydryl of hemoglobin with iodoacetamide and 2,2′-, and
4,4′- dithiodipyridine is much slower when the hemoglobin is bound by haptoglobin than …

BL Malchy abstract: The reactivityof the amino groups of the five histones towards acetic
anhydride has been measured and with the exception of histone IIb2 the reactivities are very …

B. Malchy, t H. Dugas, § F. Ofosu, 1'and Ian CP Smith* abstract: The reaction of haptoglobin
with hemoglobin spin-labeled at cysteine-/393 with (V-(l-oxyl-2, 2, 5, 5-tetramethyl-3-…
