This amino group reacts specifically with a variety of electrophiles, thereby allowing other chemical species to be attached to the oligonucleotide. This chemistry has been utilized to synthesize several fluorescent derivatives of an oligonucleotide primer used in DNA sequence analysis by the dideoxy (enzymatic) method. The modified primers are highly fluorescent and retain their ability to specifically prime DNA synthesis. The use of these fluorescent primers in DNA sequence analysis will enable DNA sequence analysis to be automated. INTRODUCTION DNA sequence determination is one of the most fundamental tools of modern molecular biology. Two methods for DNA sequence analysis exist and are in widespread use, the chemical degradation method of Maxam and Gilbert (1), and the enzymatic method of Sanger (2, 3). Although these methods are extremely powerful, they are also very laborious, time consuming, expensive, and require the use of hazardous and unstable radioisotopes. Any method for reducing or eliminating these problems would have a major impact upon molecular biology.

Combined with Nano Drug Delivery System for Pulmonary A
www.nature.com/scientificreports OPEN Innovative therapeutic strategy using prostaglandin I 2 agonist (ONO1301) combined with nano drug delivery system for pulmonary arterial hypertension Tomomitsu Kanaya1, Shigeru Miyagawa1, Takuji Kawamura1, Yoshiki Sakai1, Kenta Masada1, Nobutoshi Nawa2, Hidekazu Ishida2, Jun Narita2, Koichi Toda1, Toru Kuratani1 & Yoshiki Sawa1* Clinical outcomes of pulmonary arterial hypertension (PAH) may be improved using targeted delivery system. We investigated the efcacy of ONO1301 (prostacyclin agonist) nanospheres (ONONS) in Sugen5416/hypoxia rat models of PAH. The rats were injected with saline (control) or ONONS (n = 10, each) on days 21 and 28, respectively. Hepatocyte growth factor (HGF)-expressing fbroblasts and infammatory cytokines were measured. Cardiac performance was assessed and targeted delivery was monitored in vivo, using Texas red-labeled nanoparticles. Compared with control, HGF-expressing fbroblasts and HGF expression levels were signifcantly higher in the ONONS group, while the levels of interleukin-6, interleukin-1β, transforming growth factor-β, and platelet-derived growth factor were lower. Histological assessment revealed signifcant amelioration of the percent medial wall thickness in pulmonary vasculature of rats in the ONONS group. Rats in the ONONS group showed decreased proliferating cell nuclear antigen-positive smooth muscle cells and improved right ventricle pressure/left ventricle pressure. No diference was seen in the accumulation of Texas red- labeled nanoparticles in the brain, heart, liver, and spleen between PAH and normal rats. However, a signifcant area of nanoparticles was detected in the lungs of PAH rats. ONONS efectively ameliorated PAH, with selective delivery to the damaged lung. Idiopathic pulmonary artery hypertension (IPAH) is a progressive disease characterized by an elevation of pulmonary vascular resistance, ultimately resulting in right ventricular failure and death.

Texas Red Protein Labeling Kit Fluorescent Labeling of Thiol Groups
Texas Red Protein Labeling Kit Fluorescent labeling of thiol groups Cat. No. Amount Description: Fluorescence techniques have become a major tool in biological FP-202-TXR 3 reactions sciences. Fluorescent proteins such as GFP and DsRed fused to the protein of interest (POI) allow expression analysis and in vivo protein localization. Their application however, is limited due to the large molecular weight of those fusion proteins. Furthermore, the 1.2 1.2 associated molecular biology is tedious and time-consuming. Small fluorophores, covalently attached to the POI, may help to 1.0 1.0 overcome this problem. The most common labeling method for proteins is amine modification. Amine-reactive fluorophores such 0.8 0.8 as NHS-esters readily react with lysines, present at the surface of 0.6 0.6 the POI, resulting in a stable covalent bond.
