The synthesis of a linear polyisobutylene is achieved for the first time by free radical polymerization. reaction was performed in environmentally friendly conditions, i.e., an aqueous medium using cyclodextrin solubilizer, around room temperature. This mild and straightforward polymerization resulted predominantly polymer with low dispersity. Isobutylene also copolymerized acrylamide via this ...

The origins of the recombinant DNA technology can be traced back to the discovery of restriction enzymes and the generation of the first recombinant DNA molecule over 40 years ago (1–3). Since then, and with the emergence of PCR, scientists have generated a number of elegant cloning systems that enable the manipulation of DNA fragments in various ways (for recent reviews see Refs 4–7). Some rem...

High risk human papillomaviruses (HR-HPVs) are associated with increased risk of normal cervical cells developing to dysplasia and cervical carcinoma. Therefore, HR-HPV DNA testing can predict an endpoint of cervical carcinogenesis that is earlier than the development of cervical abnormalities. Not only the sensitivity of methods but also the amount of HPV DNA are very important and might be pa...

This work develops a loop-mediated isothermal amplification (LAMP) assay that detects the presence of bacterial pathogens (Pasteurella multocida, Mannheimia haemolytica, and Histophilus somni) for bovine respiratory disease complex (BRD) in crude nasal samples. Diagnosing BRD involves physical examination cattle expressing symptoms linked to disease. Unfortunately, these are not unique alone do...

poly(vinyl acetate) is synthesized via solution polymerization, and then it is converted to poly(vinyl alcohol) by alkaline alcoholysis. the aim of the work study was to investigate statistically the  influence of reaction variables in vinyl acetate polymerization, the conversion of this monomer to polymer, degree of branching of acetyl group in poly(vinyl acetate), as well as the molecular wei...

Quantitative polymerase chain reaction is the current "golden standard" for quantification of nucleic acids; however, its utility is constrained by an inability to easily and reliably detect multiple targets in a single reaction. We have successfully overcome this problem with a novel combination of two widely used approaches: target-specific multiplex amplification with 15 cycles of polymerase...

Introduction. Polymerase chain reaction (PCR)-based diagnostic tests use purifi ed nucleic acids (NAs) from clinical samples. The NAs cation step adds time, cost, and aff ects the quality of testing. objective this study was to develop a protocol for direct saliva in genetic markers, without acids. Methods. PCR, real-time RT-PCR isothermal amplifi were used detection Results. We report markers ...

Background: Formation of secondary structure such as DNA hairpins or loops may influence molecular genetics methods and PCR based approaches necessary for genetic engineering, in addition to gene regulation. Materials and Methods: A polymerase chain reaction with splice overlap extension (SOE-PCR) was used to create fully synthetic 1F5 chimeric anti-CD20 heavy- and light-chain genes. The chi...
