Aplicativo

• Para determinação quantitativa de ureia e avaliação dos efeitos de drogas no metabolismo da ureia.

Características principais

• Sensível e preciso. Use amostras de 5 μL. Faixa de detecção linear de 0,08 mg / dL (13 μM) a 100 mg / dL (17 mM) de uréia em ensaio de placa de 96 poços.
• Simples e de alto rendimento. O procedimento envolve a adição de um único reagente de trabalho e incubação por 20 min. Pode ser prontamente automatizado como um ensaio de alto rendimento para milhares de amostras por dia.

Mais detalhes

•  Uréia é produzido principalmente no fígado e segregado pelos rins. A uréia é o principal produto final do catabolismo protéico em animais. É o principal veículo para a remoção da amônia tóxica do corpo. A determinação da uréia é muito útil para o clínico avaliar a função renal dos pacientes. Em geral, os níveis aumentados de ureia estão associados a nefrite, isquemia renal, obstrução do trato urinário e certas doenças extra-renais, por exemplo, insuficiência cardíaca congestiva, doenças hepáticas e diabetes. Níveis diminuídos indicam insuficiência hepática aguda ou podem resultar de terapia com fluidos parenteral muito vigorosa. Procedimentos simples, diretos e prontos para automação para medir a concentração de ureia ou BUN de nitrogênio da ureia no sangue em amostras biológicas estão se tornando populares em Pesquisa e Descoberta de Medicamentos. O kit de ensaio de ureia da BioAssay Systems foi projetado para medir a ureia diretamente em amostras biológicas sem qualquer pré-tratamento. O método de Jung aprimorado utiliza um reagente cromogênico que forma um complexo colorido especificamente com a uréia. A intensidade da cor, medida em 520 nm, é diretamente proporcional à concentração de uréia na amostra. A formulação otimizada reduz substancialmente a interferência de substâncias nas amostras brutas.
