Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Procedures selected from the work of Bjornsson and Karlsson1,2 for the quantitation of sulfated glycosaminoglycans with Alcian Blue were modified and adapted to the measurement of this type of polysaccharide in bovine skin. Modifications include: (1) pulverization of the skin under liquid nitrogen, (2) brief, gentle digestion of the skin with collagenase, (3) the use of a variety of Alcian Blue widely used in histologic work, (4) the recipe for the preparation of the Alcian Blue reagent solution, (5) determination of suitable sample size, volumes of reagent solutions, incubation times, duration of centrifugation, etc. The procedure developed yields linear results for 50-300 mg samples of skin; the relative standard deviation for the procedure is +-15%.

Immunochemical estimation of the decorin core-protein content of preparations of bovine decorin / S. M. Mozersky in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. XCIX, N° 7 (07/2004)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. XCIX, N° 7 (07/2004) . - p. 280-284 Titre : Immunochemical estimation of the decorin core-protein content of preparations of bovine decorin Type de document : texte imprimé Auteurs : S. M. Mozersky, Auteur ; William N. Marmer, Auteur ; Renée J. Wildermuth, Auteur Année de publication : 2004 Article en page(s) : p. 280-284 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : An indirect sandwich ELISA procedure has been developed for estimation of the decorin core-protein content of preparations of bovine decorin. A mouse anti-bovine decorin antibody is used as the capture antibody, and a rabbit anti-bovine decorin antibody as the detecting antibody. Goat anti-rabbit immunoglobulin G (IgG) labeled with horseradish peroxidase is used to react with the detecting antibody. The peroxidase substrate orthophenylenediamine (OPD), when exposed to the (bound) enzyme in the presence of peroxide, yields a soluble product with an absorbance maximum (in acidic medium) at 492 nm. The absorbance of the solution at this wavelength thus reflects the amount of decorin core-protein in the decorin preparation that is recognized by both the capture antibody and the detecting antibody.

Leather made from the hides of double-muscled cattle has satisfactory physical characteristics / S. M. Mozersky in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. XCVI, N° 10 (10/2001)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. XCVI, N° 10 (10/2001) . - p. 393-397 Titre : Leather made from the hides of double-muscled cattle has satisfactory physical characteristics Type de document : texte imprimé Auteurs : S. M. Mozersky, Auteur ; Susan K. Iandola, Auteur ; William N. Marmer, Auteur Année de publication : 2001 Article en page(s) : p. 393-397 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Because of the relatively high efficiency with which they produce lean meat, two breeds of cattle which exhibit a high frequency of muscle hypertrophy (mh, commonly referred to as "double muscling"), viz., Piedmontese and Belgian Blue, are being considered for commercial breeding as beef animals. Double muscling results from a genetic deficiency of myostatin, the protein which normally regulates, i.e., limits, muscle growth. Since "double-muscled" animals have a somewhat larger than normal physique, and since the effect of myostatin deficiency is reasonably presumed to include hypertrophy of muscle tissue in the hide, it became important to determine whether the hides of such animals are affected by the condition and would yield leather with unusual, e.g., deficient, physical characteristics. To address this question the physical characteristics of leathers made from the hides of homozygous normal (+/+), homozygous myostatin deficient (mh/mh), and heterozygous (+/mh) cattle were compared to each other. No significant differences between the groups were found, except that leather made from mh/mh cattle had a slightly greater stiffness than leather made from +/+ cattle. Double muscling thus poses no threat of harm (or promise of substantial benefit) to the leather manufacturer which would require monitoring hides from animals endowed with this condition.

Measurement of collagenase activity in the tannery and in the laboratory I. the assay medium / S. M. Mozersky in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. LXXXX, N° 12 (12/1995)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. LXXXX, N° 12 (12/1995) . - p. 357-364 Titre : Measurement of collagenase activity in the tannery and in the laboratory I. the assay medium Type de document : texte imprimé Auteurs : S. M. Mozersky, Auteur ; David G. Bailey, Auteur Année de publication : 1995 Article en page(s) : p. 357-364 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : A commercially available acidic solution of pepsin-treated porcine skin collagen designed for cosmetic use was shown to be suitable as a substrate for viscometric assay of collagenase activity when adjusted to near neutrality and diluted with the proper buffer to a collagen concentration of 1.5 to 4.5 g/L. The buffer contains tris(hydroxymethylamino) methane (tris), citrate, and calcium (ca2+). The pH of the assay solution is 6.8. The assay solution can be supplemented with NaCl up to a concentration of at least 0.4M and the pH can be raised to at least 8.5. Pepsin treatement of calfskin colagen yields a product whose viscometric behavior in the presence of collagenase is virtually identical to that of the commercial porcine product.

Removal of available decorin core-protein from powdered bovine hide by treatments used to process intact hides into leather / S. M. Mozersky in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. CII, N° 7 (07/2007)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. CII, N° 7 (07/2007) . - p. 222-226 Titre : Removal of available decorin core-protein from powdered bovine hide by treatments used to process intact hides into leather Type de document : texte imprimé Auteurs : S. M. Mozersky, Auteur ; Renée J. Latona, Auteur ; William N. Marmer, Auteur Année de publication : 2007 Article en page(s) : p. 222-226 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Using a modification of a previously developed sandwich Elisa procedure to measure decorin core-protein (DCP), we determined the available decorin content of a sample of raw powdered bovine hide before and after treatment with the reagents used in the early steps of the process for converting a hide into leather. (“Available” refers to the availability of the decorin for interaction with the antibodies used in the Elisa procedure.) We found approximately 0.16 mg available decorin/g hide in the raw powdered hide. Treatment with liming reagents resulted in a drop of 99.7 +0.3/-0.6 % in available decorin content. The results suggest further investigations on intact hide samples to establish whether decorin removal is restricted by diffusion.
