The purification and partial characterization of the melanophore-dispersing hormone of Uca pugilator
TLDR
Two major peaks of melanophore-dispersing activity were isolated by a combination of gel filtration on Sephadex G-25 and successive ion exchange chromatography on CM- and DEAE-cellulose, and the homogeneity of MDH-1 was determined in two different paper chromatography and paper electrophoresis systems.About:

Pigment-dispersing hormones: a novel family of neuropeptides from arthropods.
K R Rao,John P. Riehm +1 more
TL;DR: This report summarizes recent work on the chemistry and structure-activity relationships of crustacean chromatophorotropic pigment-dispersing hormones (PDHs) and the identification of structurally related peptides from insects and indicates that at least 50% of the amino acid sequence appear to be conserved.

Isolation and sequence analysis of a pigment-dispersing hormone from eyestalks of the crab, cancer magister
TL;DR: The characterized Cancer PDH is structurally identical to an octadecapeptidePDH of Uca pugilator, but differs from the PDH of Pandalus borealis at positions 3, 4, 11, 13, 16, and 17.

Fluorescamine: A Reagent for Assay of Amino Acids, Peptides, Proteins, and Primary Amines in the Picomole Range
Sidney Udenfriend,Stanley Stein,Peter Böhlen,Wallace Dairman,Willy Leimgruber,Manfred Weigele +5 more
TL;DR: Fluorescamine is a new reagent for the detection of primary amines in the picomole range that is almost instantaneous at room temperature in aqueous media and the products are highly fluorescent, whereas the reagent and its degradation products are nonfluorescent.

Study of the dansylation reaction of amino acids, peptides and proteins
C. Gros,B. Labouesse +1 more
TL;DR: It is shown that a compromise for optima conditions of dansylation (pH and temperature) may be found, taking into account the rate of hydrolysis and the pK of the group to be dansyated.

Microheterogeneity of the carbohydrate group of Aspergillus oryzae α-amylase
Jeffrey F. McKelvy,Yuan C. Lee +1 more
TL;DR: In this paper, α-amylase from Aspergillus oryzae was purified by gel filtration and ion-exchange chromatography, and showed that the mixture contained glucosamine, mannose, galactose, arabinose, and xylose.

Structure of a light-adapting hormone from the shrimp, Pandalus borealis
TL;DR: The structure of a light-adapting hormone of the shrimp, Pandalus borealis, has been determined by sequence analysis by the dansyl-Edman method of the intact hormone and of isolated tryptic and thermolytic peptides.

Purified hormones from the crustacean eyestalk and their physiological specificity.
TL;DR: A third well characterised hormone, hyperglycaemic hormone (HGH), increases glucose concentration of the blood, but such hyper glycaemic responses may vary in cross tests among crustacean species4–6.
