MATERIALS 6x Gel-loading buffer Agarose solutions (please see Step 3) DNA samples DNA size standards Samples of DNAs of known size are typically generated by restriction enzyme digestion of a plasmid or bacteriophage DNA of known sequence. Alternatively, they are produced by ligating a monomer DNA fragment of known size into a ladder of polymeric forms. DNA staining solution For a discussion of...
We find new facet-defining inequalities for the linear ordering polytope generalizing the well-known Möbius ladder inequalities. Our starting point is to observe that the natural derivation of the Möbius ladder inequalities as {0, 1 2 }-cuts produces triangulations of the Möbius band and of the corresponding (closed) surface, the projective plane. In that sense, Möbius ladder inequalities have ...
A unique DNA scaffold was prepared for the one-step self-assembly of hierarchical nanostructures onto which multiple proteins or nanoparticles are positioned on a single template with precise relative spatial orientation. The architecture is a topologically complex ladder-shaped polycatenane in which the "rungs" of the ladder are used to bring together the individual rings of the mechanically i...
Background: Molecular DNA markers are one of the most important tools in molecular biology labs. The size of DNA molecules is determined by comparing them with known bands of markers during gel electrophoresis. There are many different protocols to produce these kinds of molecular markers. In this study we have suggested an efficient strategy to produce molecular weight markers in industrial pr...
TAS-103, a new anticancer drug, induces DNA cleavage by inhibiting the activities of topoisomerases I and II. We investigated the mechanism of TAS-103-induced apoptosis in human cell lines. Pulsed field gel electrophoresis revealed that in the leukemia cell line HL-60 and the H(2)O(2)-resistant subclone, HP100, TAS-103 induced DNA cleavage to form 1-2-Mb fragments at 1 h to a similar extent, in...
صنعتی شدن جوامع منجر به استفاده از آلاینده هایی شده که با ورود به آب، هوا و اکوسیستم محیط زندگی بشر را تحت تاثیر قرار داده است. یکی از این آلاینده ها پارانونایل فنل می باشد که در فرمولاسیون و ساخت بسیاری از محصولات مورد استفاده در زندگی مدرن از جمله مواد پلاستیکی، لوازم آرایشی و شوینده ها استفاده می شود. این آلاینده پس از ورود به بدن موجود زنده، قابلیت تجمع در بافت ها را داشته و طی بررسی های گو...
An unusual antigen composed of tandemly repeated protein units was cloned from the filarial parasite Dirofilaria immitis. The antigen was initially identified by screening a lambda gt11 cDNA library with serum from dogs immunized with irradiated D. immitis third-stage larvae. DNA sequence analysis of the cDNA clone, Di5, revealed a continuous open reading frame composed of two 399-base-pair rep...
