M Mahmoudi Rad,F Zaini,M Pezeshki,P Kordbacheh
Iranian Journal of Public Health , 2001,
Abstract: In the present study, we investigated total cell protein patterns of ten isolates of Trichophyton rubrum by SDS-PAGE on 12.5% polyacrylamide resolving gels. Twenty-two protein bands were detected with molecular weights in the range of 23.2 to 131.8 KD. Proteins of 23.2, 25.4, 26.7, 28.2, 30.2, 33.1, 34.7, 38,41.7, 47.9, 52.5, 56.2, 61.7, 67.6, 70.8, 75.9, 80, 84.1, 93.3, 102.3, 114.8, 131.8 were present but their frequencies varied among the isolates. Protein bands of 23.2, 38, 47.9, 52.5, 84.1 were common among the isolates and could be specific to recognize species differences. Protein analysis by SDS-PAGE could be considered a useful technique in identifying differences among the dermatophyte isolates.

Journal of Chongqing Normal University , 2012,
Abstract: "The paper discusses the effects of different means to extract the protein of eggs of Bombyx mori as well as to find the best conditions of SDS-PAGE to separate the proteins of eggs of B. mori. Trichloroacetic acid (TCA) precipitation, acetone precipitation and trichloroacetic acid-acetone (TCA-acetone) precipitation were used to extract the protein of eggs of B. mori. The protein was separated by different systems of homogeneous gel in a series of concentrations from 6% (separation gel) ~ 12%(spacer gel) to 6%(separation gel) ~ 15%(spacer gel) to search the most appropriate way of extracting the protein of eggs of B. mori and the conditions of electrophoresis. Protein maps of different homogeneous gel concentrations (6% ~ 12%, 6% ~ 15%) and different protein extractionmethods were obtained. Then the efficiency of the different maps was compared. It showed that removing the salt by TCA-acetone method and dissolving the protein by the lysis buffer consists of urea (9 mol·L-1)、CHAPS(4%)and DTT(1%) were the best way to ex-tract the proteins of eggs of B. mori. Meanwhile the suitable gradient of the homogeneous gel is 6% ~ 12%. The optimized method wasexplicated to analysis the differences between the eggs of the normal B. mori and whose infected by Nosema bombycis. Finally, the 66 kD protein band and 85 kD protein bands were gained and speculated to associate with the infection of Nosema bombycis."

E. A. Kamel,M.H.A. Loutfy
Pakistan Journal of Biological Sciences , 2001,
Abstract: SDS-PAGE of seed protein, petiole anatomy and leaf cuticular features were used to re-assess the taxonomic relationships between eight taxa presenting four genera of the Lauraceae, viz. Apollonias Nees (one species), Cinnamomum Schaeff (three species), Laurus L. (two species) and Persea Mill. (one species with two varieties). The data obtained were analyzed by Ntsys-pc program package using the UPGMA clustering method. The produced dendrograms were discussed. SDS-PAGE analysis showed a close relationship between Apollonias and Persea. Domatia and certain unique features were recorded in the leaf epidermis of Apollonias. Considerable variations were evident between the two varieties of Persea and a re-evaluation of their status was suggested. The validity of SDS-PAGE of seed protein criteria in the Lauraceae was confirmed

Tehran University Medical Journal , 1999,
Abstract: In the present study, we investigated total cell protein patterns of ten isolates of Epidermophyton Floccosum Var.pigmented by SDS-PAGE on 10% polyacrylamide resolving gels. Densitometric analysis of the gels allowed to detect more than 31 clearly detectable mycelial protein bands with molecular weights in the range of 12 to 98 KD proteins of 12.5, 13.5, 14.4, 16, 18.4, 19.7, 20.1, 23.5, 26, 27, 29, 30, 32.5, 34, 35.5, 37, 39.5, 40.5, 43, 47.5, 50, 63, 68, 75, 79, 82.5, 74.5, 90, 94, 96, 97-5 KD were present but their frequencies varied among the isolates. Protein bands of 18.4, 19.7, 20.1, 27, 29, 34, 37, 43, 47.5, 50, 63, 79, 94, KD were stronger and common among the isolates and could be specific to recognize genus differences. Protein analysis by SDS-PAGE could be considered an useful technique in identifying differences among the dermatophyte isolates.
Genetic Diversity in Brassica Species Using SDS-PAGE Analysis
Rahman Md. Mukhlesur,Yutaka Hirata
Journal of Biological Sciences , 2004,
Abstract: Eighty five different cultivars of Brassica rapa, B.juncea, B.napus, B. carinata, B. oleracea and hexaploid Brassica, collected from Bangladesh, Japan, China and Denmark, were analyzed for seed and leaf protein variations by SDS-PAGE to identify the polymorphic genetic markers for evaluation of genetic resources. Ten polymorphic markers were identified from seed protein and no identifiable polymorphic band was found from leaf protein. However, polymorphic markers clearly distinguished these Brassica species. Brassica rapa var. `yellow sarson` of Bangladesh origin showed uniquely identifiable four polymorphic bands for seed protein in contrast to the other B.rapa of brown-seeded type. The Bangladeshi and Japanese cultivars of B. rapa differed among protein quantity. Analytical results of SDS-PAGE for seed protein showed that hexaploid Brassica has the highest indices, such as % of polymorphic band, the degree of phenotypic diversity (Ho), diversity value for genetic marker (HEP) and the sum of the effective number of alleles (SENA). The genetic diversity values of hexaploid Brassica were followed by amphidiploid (B. napus, B. juncea, B. carinata) and diploid (B. oleracea, B. rapa) species, respectively.
小麦地方品种SDS-PAGE分析  [PDF]
华北农学报 , 1992, DOI: 10.3321/j.issn:1000-7091.1992.02.006
Abstract: 用十二烷基硫酸钠—聚丙烯酰胺凝胶电泳(SDS—PAGE),分析了河北省611份小麦地方品种的麦谷蛋白高分子量(HMW)亚基构成,并依据SDS—PAGE图谱对地方品种的同名异种作了鉴别分析。结果表明,河北省地方品种的麦谷蛋白HMW亚基分布是很单一的,且类型较少,以Glu-Alc(频率97.1%)、Glu-Blb(80.7%)和Glu-D1a(90.5%)为其优势等位基因,表明地方品种烘烤品质一般较差,同时又具有很特殊的亚基类型:有两个频率较高的异常类型,其等位基因可能是最近公布的Glu-Blaj(只编码8亚基)和Glu-Dlk(只编码2亚基),说明我国古老地方品种是一特殊小麦群体类型。同名品种中具有相同SDS—PAGE图谱的品种认为是同一基因型,具有很高的遗传相似性。虽然其中有少数其它基因型,我们认为它们是种植过程中自然变异的结果。

Archives of Biological Sciences , 2011, DOI: 10.2298/abs1104965d
Abstract: Glutamine synthetase (GS) is a key nitrogen-assimilating enzyme in plants and a target for the broad-spectrum herbicide glufosinate. Understanding its kinetic and structural properties is of major agricultural importance. Spinach (Spinacia oleracea) is classified as a plant expressing only chloroplastic GS activity. We have analyzed soluble proteins in the spinach by coupling native polyacrylamide gel electrophoresis (PAGE)-activity detection, based on phosphate precipitation, with SDS-PAGE/immunoblotting. One cytosolic (GS1) isoform from the roots and two chloroplastic (GS2) isoforms expressed in leaves were resolved by native PAGE. The identity of the obtained bands was established by the application of GS-specific inhibitors, L-methionine sulfoximine and glufosinate. Examination by sodium dodecyl sulfate (SDS)-PAGE/ Western analysis with anti-GS antibodies, confirmed the identity of the active bands and revealed that both chloroplastic isoforms are composed of 44 kDa subunits, while the cytosolic isoform consists of 40 kDa subunits. The presence of more GS2 isozymes than encoded in the spinach genome is discussed in terms of posttranslational modifications.

Pakistan Journal of Biological Sciences , 2007,
Abstract: Wheat seed-storage proteins represent not only an important source of food and energy but it is also involved in the determination of bread-making quality. Wheat grains of thirteen wheat varieties were collected from different ecological regions of Pakistan. The variability of seed storage-proteins was analyzed by using SDS-PAGE electrophoresis. Electrophorogram for each variety was scored and presence or absence of each band noted and entered in a binary data matrix. Based on electrophoresis band spectra, Jaccard‘s Similarity Index (JSI) was calculated. Genetic diversity of wheat was evaluated by constructing the dendrogram for High Molecular Weight (HMW) and Low Molecular Weight (LMW) gluten subunit bands. It is concluded that seed storage protein profiles could be useful markers in the studies of genetic diversity and classification of adapted cultivars, thereby improving the efficiency of wheat breeding programs in cultivar development especially in developing countries like Pakistan.
