Background & Aims: Tyrosinase is the most important enzyme in the production of pigments of the skin, eyes, and hair follicles. The enzyme is encoded by tyrosinase gene (TYR) or oculocutaneous albinism type 1A (OCA1A). Mutations in TYR gene result in pigmentation disorders such as albinism in humans. In view of the large number of mutations reported in this gene, the aim of this study was to id...

background and objective:determination of her2 gene is crucial in breast carcinoma management and prognosis, as her2 alterations are linked to a shorter disease-free period, overall survival and resistance to tamoxifen anti-estrogen therapy and other chemotherapy regimens, regardless of the nodal or hormone receptor status. this study aimed to estimate her2 gene status of infiltrative mammary c...

Genomic DNA extracted from bovine mummified tissue is valuable material for detection of some genes that may contribute to fetal abnormalities. In this study bovine genomic DNA was extracted from the hardened tissue samples of ten bovine mummified fetuses. The amount of genomic DNA extracted from 2 g of the mummified tissues by the phenol/chloroform-ethanol method was low (less than 4 microg/ml...

in view of the fundamental role of genetics in development of obesity, the present study aimed to investigate the single nucleotide polymorphism of some obesity-related genes among a subset of obese women living in tabriz, iran. for this purpose, 70 eligible obese women (aged 18-45 years) were genotyped for the uncoupling protein-1 (ucp-1) -3826a>g, ß3-adrenergic receptor (ß3adr) trp64arg, lept...

Background: Listeria is a Gram-positive, non-spore forming, facultative anaerobic intracellular bacterium. The most important pathogens in mammals include Listeria monocytogenes and Listeria ivanovii. The former generally causes disease and death in both humans and animals while the latter performs sporadically and primarily causes illness in ruminant...

Background: Taq DNA polymerase is a very important enzyme for molecular biological studies such as DNA amplification and DNA sequencing by the PCR. It is a standard enzyme that is used in 90% of molecular biology labs today. The aim of this study was to produce Taq DNA polymerase enzyme in E. coli by a reliable, practical, simple and low cost method. Materials and Methods: In this study, the T...

Blinatumomab, the bispecific T cell engager, has been demonstrated as the most successful BsAb to date. Throughout the past decade, vector design has great importance for the expression of monoclonal antibody in Chinese hamster ovary (CHO) cells. It has been indicated that expression plasmids based on the elongation factor-1 alpha (EF-1 alpha) gene and DHFR selection marker can be highly effect...
