Proteins are essential constituents of all organisms; both egg white proteins and egg yolk are source of protein. The aim of this study was conducted to perform preliminary studies to analyses and compare egg white proteins and yolk proteins from different avian species (guineafowl, dwarf hens, local hen, Shami, turkey, duck, geese, partridge and quail) via or with SDS-PAGE (Sodium Dodecyl Sulfate–Polyacrylamide Gel Electrophoresis ). 18 Fresh eggs of different poultry species (guineafowl, dwarf hens, local hen, Shami, turkey, duck, geese, partridge and quail) were collected from various farms in the Sulaimani province. Data on egg proteins were analyzed using Statistical Xlstate used for dendrogram construction and PCA. The main egg white proteins were Ovomicin, Ovotransferrin, Ovalbumin, Flavoprotein, α- chymotrypsinogen, and Trypsin inhibitor. The main lipoproteins were Apovitellenin VI, Apovitellenin Vb, Apovitellenin V, Apovitellenin IIIa, Apovitellenin III, Apovitellin 7, B-Livetin, Apovitellenin IIa, Apovitellenin II, and Apovitellenin I. All these lipoproteins were observed in the nine birds species. The egg white proteins and yolk lipoproteins for nine species were examined. It can be concluded the large differences were found in a mount of egg white proteins and yolk lipoproteins of the nine species of birds.

SummaryCongenitally abnormal fibrinogen Osaka III with the replacement of γ Arg-275 by His was found in a 38-year-old female with no bleeding or thrombotic tendency. Release of fibrinopeptide(s) by thrombin or reptilase was normal, but her thrombin or reptilase time in the absence of calcium was markedly prolonged and the polymerization of preformed fibrin monomer which was prepared by the treatment of fibrinogen with thrombin or reptilase was also markedly defective. Propositus' fibrinogen had normal crosslinking abilities of α- and γ-chains. Analysis of fibrinogen chains on sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) in the system of Laemmli only revealed the presence of abnormal γ-chain with an apparently higher molecular weight, the presence of which was more clearly detected with SDS-PAGE of fibrin monomer obtained by thrombin treatment. Purified fragment D1 of fibrinogen Osaka III also seemed to contain an apparently higher molecular weight fragment D1 γ remnant on Laemmli gels, which was digested faster than the normal control by plasmin in the presence of [ethy-lenebis(oxyethylenenitrilo)]tetraacetic acid (EGTA).

ABSTRACT Bartonella species can be differentiated by microimmunofluorescence assay, sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), and immunoblotting with murine polyclonal antisera to Bartonella henselae, B. quintana, B. elizabethae, and B. bacilliformis. A pairwise comparison on the basis of SDS-PAGE protein profiles demonstrated similarity values for proteins of different Bartonella species ranging from 28.6 to 86.4%. Antigenic relationships revealed by immunoblotting with murine antisera were equivalent to those of proteins observed by SDS-PAGE. A dendrogram obtained on the basis of protein bands of SDS-polyacrylamide gels showed that Bartonella species could be divided into three groups. B. bacilliformis was distinct from all otherBartonella species; B. grahamii, B. taylorii, B. doshiae, and B. vinsoniiformed a cluster, as did B. henselae, B. quintana, B. elizabethae, and B. clarridgeiae. These relationships were consistent with those revealed by parsimony trees derived from 16S rRNA and gltAgene sequencing. SDS-PAGE analysis showed that 120-, 104-, 85-, 71-, 54-, 47-, 40-, 33-, 30-, and 19-kDa proteins were present in all species, with the 54-kDa protein being the most dominant. Proteins with a molecular mass of less than 54 kDa allow the differentiation of species and are a possible target for future species-specific antibodies and antigens.

Analysis by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of crude extracts of disease-free and Didymascella thujina-infected foliage of western red-cedar revealed differences in several protein bands and suggests that distinct proteins of D. thujina origin can be identified by SDS-PAGE.

Perbedaan proses penyembelihan dapat mempengaruhi respon fisiologis hewan yang dapat diidentifikasi melalui pola ekspresi protein. Dalam penelitian ini dilakukan analisis awal protein daging untuk menganalisis pengaruh perbedaan metode penyembelihan, yaitu metode halal dan nonhalal. Penelitian menggunakan enam ekor tikus Wistar sebagai hewan uji. Kelompok uji pertama diberi perlakuan penyembelihan dengan metode halal, yaitu dengan pemotongan pembuluh darah pada leher hewan. Kelompok kedua diberi perlakuan penyembelihan secara nonhalal, yaitu dilakukan metode dislokasi servikal. Analisis profil protein daging dilakukan dengan menggunakan Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis (SDS-PAGE). Hasil SDS-PAGE menunjukkan beberapa pita protein tereskpresi pada berat molekul 116; 55; 48; 45; 41; 26; dan 17 kDa (kiloDalton), sedangkan hasil kuantifikasi pita protein menunjukkan sampel protein daging hasil penyembelihan nonhalal memiliki kuantitas lebih tinggi daripada sampel protein daging hasil penyembelihan halal. Kuantitas protein yang lebih tinggi pada penyembelihan nonhalal diduga karena lepasnya protein tertentu ke dalam sistem metabolisme hewan sebagai akibat dari respon stres yang diberikan.Kata kunci: elektroforesis; halal; nonhalal; protein; SDS-PAGE
