Chedekel M, Ahene A, Zeise L
Pigment Cell Res . 1992 Nov; 5(5 Pt 1):240-6. PMID: 1287627
Natural melanins are composed of two distinct portions; a protein fraction and a chromophoric backbone. There is no unequivocal evidence for covalent bonding between these two fractions, and standard protocols...

Zeise L, Chedekel M
Pigment Cell Res . 1992 Nov; 5(5 Pt 1):230-9. PMID: 1287626
Melanin isolated from the ink sac of Sepia officinalis (Sepia melanin) has been proposed as a standard for natural eumelanin, and a standard mild isolation and purification protocol for Sepia...

Chedekel M, Murr B, Zeise L
Pigment Cell Res . 1992 Sep; 5(3):143-7. PMID: 1409451
Melanin isolated from the ink sac of cuttle fish (Sepia melanin) is a proposed standard for natural eumelanin. Sepia melanin isolated by a standard protocol was submitted for both elemental...

Kollias N, Sayre R, Zeise L, Chedekel M
J Photochem Photobiol B . 1991 May; 9(2):135-60. PMID: 1907647
This paper is an attempt to summarize the current state of information on melanin and epidermal melanin pigmentation (EMP) as photoprotective agents. The chemistry and biochemistry of melanin (the particle)...

Lambert C, Chacon J, Chedekel M, Land E, Riley P, Thompson A, et al.
Biochim Biophys Acta . 1989 Oct; 993(1):12-20. PMID: 2804118
The rate constants associated with the series of successive transient absorptions initiated by one-electron oxidation of 5,6-dihydroxyindole (DHI), 5,6-dihydroxyindole-2-carboxylic acid (DHICA), precursors of melanin, and N-methyl-5,6-dihydroxyindole (NMDHI), a model compound,...

Chacon J, Chedekel M, Land E, Truscott T
Biochem Biophys Res Commun . 1989 Jan; 158(1):63-71. PMID: 2783550
The one-electron reduction product of 1-methyl-4-phenyl-2,3-dihydropyridinium ion has been generated by pulse radiolysis and its absorption spectrum recorded. This radical was found to decay by second-order kinetics (2k = 9.5...

Chedekel M, Zeise L
Lipids . 1988 Jun; 23(6):587-91. PMID: 3050346
Melanocytes are cells of neural crest origin residing at the dermal-epidermal juncture. They produce specialized organelles called melanosomes within which the biochemical processes of melanization occurs. UV radiation is capable...

Pigment Cell Res . 1988 Jan; 1(5):326-31. PMID: 3237600
An antiserum against alpha-amino-(4-hydroxy-6-benzothiazolyl)propionic acid (AHBP), a major product obtained after hydriodic acid hydrolysis of pheomelanin, was raised in rabbits immunized with AHBP coupled to bovine serum albumin (BSA). The...
