Resumo:

Fluorigenic aromatic molecules have found wide application in Fluorescence Spectroscopy. Commercially available fluorigenic reagents have been used to detect amines, amino acids, peptides and proteins. Orthophthalaldehyde (OPA) is an aromatic dialdehyde which is specific for a primary amino group. Three polyaromatic dialdehyde molecules similar to this compound have been synthesised and investigated for their analytical applications. They are: (1) naphthalene-2,3- dicarboxaldehyde (NDA), (2) 1-phenylnaphthalene-2, 3- dicarboxaldehyde (0NDA) and (3) anthracene-2,3- dicarboxaldehyde (ADA).

Resumo:

Voltage-gated potassium (Kv) channels are essential membrane proteins in modulating membrane excitability and related cellular processes. Many details associated with the voltage response are unclear, particularly the complete role of the voltage sensing domain, and not just the densely charged S4 helix. Based on its crystal structure, the Kv1.2 channel represents an ideal model in which to study these questions. This thesis investigates Kv1.2 activation and deactivation gating, using the voltage clamp fluorimetry technique. This technique utilizes an environmentally sensitive fluorophore

The use of fluorescent molecules as probes of protein conformation is recognized as a technique which provides very specific information and has been applied, in recent years, to the study of the role of tropomyosin (TM) in the regulation of contractile processes. The isolation and sequencing of TM from horse blood platelets (P-TM) has shown it to be different from muscle TM, especially near the NH₂-and COOH-termini. These differences have been suggested to weaken end-to-end interaction of P-TM molecules. TM's are two chain coiled coils and P-TM has cysteine residues at the penultimate COOH-te

Although integral membrane proteins represent nearly a quarter of the genes present in both prokaryotes and eukaryotes, progress in this area of research is often hindered due to the nature of their hydrophobic environment. Elucidating the folding pathway of these proteins is essential to understand many membrane mediated biological processes such as signal transduction, ion transport and chemotaxis. The wealth of structural and genetic information on bacteriorhodpsin renders it an ideal model system for the study of membrane proteins. Detailed studies however, necessitate efficient methods fo

For many years there has been a great interest among the scientific community in the study of the hydroxyl radical, HO. This interest stems from the fundamental role played by this molecule in the photochemistry of the atmosphere, mainly as a cleansing agent of environmental pollutants. Knowing the concentration of the radical would enable scientists to corroborate current atmospheric models and to predict future trends in the atmosphere. Even though there is a great interest in the determination of atmospheric concentrations of this molecule, the task has been very difficult. This is mainly d

Nitrogen oxides control the global formation of ozone in the lower atmosphere and influence the much higher levels of ozone formed in areas subjected to photochemical air pollution. As an important member of the nitrogen oxide family, N02 plays a significant role in serving as the only known source of ozone (through photolysis) in the lower atmosphere and as sink for HO via the formation of nitric acid. Ozone can be destroyed by reaction with another member of the nitrogen oxide family, nitric oxide (NO), to reform N02. This cycle between NO, N02 and 03 is known as the NOx-03 photostationary s

A novel detector for ultra-high energy cosmic rays, and its prototype are discussed. It detects events with primary energy greater than 100 PeV. (1 PeV = 1000 TeV; 1EeV = 1000 PeV.) The detector operates by sensing the near-ultraviolet scintillation light of ionized nitrogen molecules created by the passage of ionizing particles in extensive air showers. (The concept is loosely based on the highly successful Fly's Eye detector situated at Dugway, Utah.)

All important factors such as time, pH, reagent concentration, buffers, surfactants and selected interferents have been studied with respect to the selectivity, sensitivity, precision and detection limit on the determination by using classic fluorescence spectra and their first derivation. This reagent was also used for the determination of scandium in real waters. The new reagent was shortly compared to morin and lumogallion when used for scandium.

En aquest treball s'exposen dues línies de recerca centrades en el procés de producció d'una lipasa de Rhizopus oryzae (ROL) en Pichia pastoris: la utilització de diferents tècniques de monitoratge i l'aplicació d'estratègies de cultiu que permetin millorar la producció de la ROL en una soca Mut+ d'aquest sistema d'expressió. <br/>En els cultius discontinus alimentats amb P. pastoris cal disposar d'una mesura en línia i en temps real de la concentració de substrat, el metanol. Per això es va desenvolupar un analitzador d'injecció seqüencial. Es va comprovar que aquest té una freqüència d'anàl
