Increasingly, the Cre-loxP system is being used to generate both null and conditional mutations in mice by homologous recombination in embryonic stem (ES) cells (1,3–5). The advantage of the Cre-loxP approach in generating mutations in mice, is that the gene of interest can be inactivated in any organ at a given time during the mouse’s life, thus bypassing developmental and/or pleiotropic effec...

this study was conducted to determine the electrophoretic pattern of serum protein in goats infected withbabesia ovis. serum total protein was calculated and serum electrophoresis from 15 goats naturally infectedwith b. ovis as well as same number of healthy goats was performed. microscopic examination of giemsastained peripheral blood smears revealed b. ovis infection. the parasitological diag...

background and objectives: jak2 is a nonreceptor tyrosine kinase that plays a major role in myeloid disorders. jak2v617f mutation is characterized by a g to t transverse at nucleotide 1849 in exon 12 of the jak2 gene, located on the chromosome 9p, leading to a substitution of valine to phenylalanine at amino acid position 617 in the jak2 protein. in this study we compared two molecular methods ...

Roses (Rosa indica) belong to one of the most crucial groups of plants in the floriculture industry. Rosa species have special fragrances of interest to the perfume and pharmaceutical industries. The genetic diversity of plants based on morphological characteristics is difficult to measure under natural conditions due to the influence of environmental factors, which is why a reliable fingerprin...

It is essential to analyze rare mutations in many fields of biomedical research. However, the detection of rare mutations is usually failed due to the interference of predominant wild-type DNA surrounded. Herein we describe a sensitive and facile method of detecting rare point mutation on the basis of allele-specific amplification in emulsion PCR. The identification and selective amplification ...

A universal restriction site-free cloning method has been developed to precisely insert a DNA fragment into a vector at any desired location without altering any nucleotide(s) in either the DNA fragment or the vector. The technique employs two pairs of chimeric primers, each containing a ribonucleotide. One pair of primers is used to amplify a target DNA fragment and another is used to prepare ...

MOTIVATION Before performing a polymerase chain reaction experiment, a pair of primers to clip the target DNA subsequence is required. However, this is a tedious task as too many constraints need to be satisfied. Various kinds of approaches for designing a primer have been proposed in the last few decades, but most of them do not have restriction sites on the designed primers and do not satisfy...

Pemphigus vulgaris (PV) is an acquired autoimmune blistering disease characterized by the production of autoantibodies targeting desmosomal cadherins, primarily desmoglein 1 and 3, leading to acantholysis. The etiology PV multifactorial, including genetic susceptibility. This retrospective study aimed evaluate association HLA class II alleles examine impact PV-associated on concentration anti-d...

We have compared Duffy blood group genotype distribution, as determined by polymerase chain reaction with allele-specific primers, in 68 Plasmodium vivax-infected patients and 59 non-vivax malaria controls from Rondônia, Brazil. Homozygosity for the allele Fy, which abolishes Duffy antigen expression on erythrocytes, was observed in 12% non-vivax controls but in no P. vivax patient. However, no...
