Ruthenium-caged antisense morpholinos for regulating gene expression in zebrafish embryos The photolabile group, ethyl 4-(4-(1-hydroxyethyl)-2-methoxy-5-nitrophenoxy)butanoic acid, was selected as the degradable unit because of its previous use in live cell cultures 14. As demonstrated, Ru photolinkers provide a versatile method for controlling structure and function of biopolymers. Hydroxyethyl photolinker Density: 1.333g/cm3: Boiling Point: 540. One-cell-stage zebrafish embryos microinjected with Ru-MO and incubated in the dark for 24 h developed normally, consistent with caging, whereas irradiation at 450 nm dissociated one 3-ethynylpyridine ligand ( Φ = 0.33) and uncaged the MO to achieve gene knockdown. Chemical Name: 4-4-(1-hydroxyethyl)-2-methoxy-5-nitrophenoxybutanoic acid CAS Number: 17 Molecular Formula: C 13 H 17 NO 7 Molecular Weight: 299.27700. RuBEP-caged circular morpholinos (Ru-MOs) targeting two early developmental zebrafish genes, chordin and notail, were synthesized and tested in vivo. Here, we present the first example of a visible light responsive ruthenium-based photolinker, Ru(bipyridine) 2(3-ethynylpyridine) 2 (RuBEP), which was reacted stoichiometrically with a 25mer DNA or morpholino (MO) oligonucleotide functionalized with 3′ and 5′ terminal azides, via Cu( I)-mediated Huisgen cycloaddition reactions. 2017, 134, 44380.Photochemical approaches afford high spatiotemporal control over molecular structure and function, for broad applications in materials and biological science. is focused on the ongoing development of research reagents. is supplier for 4-(4-(1-Hydroxyethyl)-2-methoxy-5-nitrophenoxy)butyric acid. Specific interactions between glucose and the polymer chains were evidenced by values of the partition coefficient higher than unity. now offers over 140,000 specialty biochemicals under our ChemCruz brand. Very good for skin, Idealworldtv, Houdahgeo vs photolinker, Native union marble. All hydrogels were also permeable to glucose and insulin, which displayed comparable diffusion coefficients (in the order of 10 −6 cm 2/s). Results showed that the swelling was dependent on the IonS (with swelling reductions up to 20–30% for IonS increases in the range 0–300 mM) and, to a lesser extent, on the pH of the surrounding medium (with swelling increments of about 10% for increasing pH in the range 2.5–11). The transport of glucose and insulin through thin hydrogel membranes was finally assessed in a modified Ussing chamber at physiological values of pH and IonS (7.4 and 150 mM, respectively). Swelling measurements in distilled water were performed to estimate the yielded crosslink density, while swelling tests at 37 ☌ in selected media allowed to analyze the mesh size changes induced by various pH and ionic strength (IonS) conditions. When the peptide is conjugated to ligands of interest, we demonstrate the photo-activated cellular uptake of a wide range of cargoes, including small fluorophores, proteins, inorganic (e.g. Several hydrogels were synthesized through UV irradiation of PEGDA solutions for different exposure times. The aim of this work was to assess the diffusive properties of poly(ethylene glycol) diacrylate (PEGDA)-based hydrogels, derived from low MW prepolymers, in view of potential biomedical applications. Product Name:4-(4-(1-Hydroxyethyl)-2-methoxy-5-nitrophenoxy)butyric acid CAS:17 Purity: 98 (HPLC) Remarks:It is used as a photolabile linker for the preparation of carboxylic acids.
