Um método para medir o metabolismo em Ordenado subpopulações de Comunidades celulares complexas usando Stable Isotope Tracing

Este protocolo descreve a reconstituição de nucleossomas contendo histonas irmã isotopicamente marcados diferencialmente. Ao mesmo tempo, nucleossomas assimetricamente pós-translacionalmente modificados pode ser gerado após o uso de uma cópia da histona premodified. Estas preparações podem ser prontamente usadas para estudar os mecanismos de modificação de diafonia, simultaneamente em ambas as histonas irmã, utilizando espectroscopia de RMN de alta resolução.

Reconstituição de Nucleosomes com Histones irmã diferencialmente Isotope-rotulados

A retina humana é composta de regiões funcionalmente e molecularmente distintas, incluindo a fóvea, mácula e retina periférica. Aqui, descrevemos um método usando o soco de biópsias e remoção manual das camadas de tecido do olho humano para dissecar e coletar estas regiões distintas da retina para análise proteômica a jusante.

Descrevemos em detalhes dois protocolos de base química para cultivo de células-tronco embrionárias do mouse. Esse novo método utiliza mecanismos sinérgicos de promover oxidação mediada por Tet (vitamina C) e reprimindo a síntese de novo de 5-metilcitosina (por PD0325901) para manter o DNA hypomethylation e pluripotência das células-tronco embrionárias do mouse.

Análise de isótopo carbono e oxigênio estável de carbonato de esmalte do dente humano e animal tem sido usado como um proxy para cada dieta e reconstrução ambiental. Aqui, nós fornecemos uma descrição detalhada e documentação visual de granel e sequencial do dente esmalte amostragem bem como pré-tratamento de amostras arqueológicas e paleontológicas.

Newcastle University.  A preparação da vitamina A estável marcada com isótopos, necessária para a técnica de diluição de isótopos de retinol, precisa estar em conformidade com os padrões de segurança alimentar. O protocolo mostra a preparação dosificada em óleo vegetal em concentrações adequadas para o sistema de administração escolhido e para a plataforma analítica aplicada.
