Visão geral

Composição: Coloide de ouro estabilizado com citrato

Tamanho do núcleo: 20nm

Absorção máx: 524nm

Partículas por ml: 6.54E+11

Utilização prevista:

Adsorção de ligandos tiolados, tais como oligonucleótidos e polietilenoglicóis. Além disso, devido à maior estabilidade, estas nanopartículas de ouro são ideais para utilização em aplicações físicas e ópticas.

Nota:

Este produto não é ideal para a adsorção de proteínas. Para nanopartículas de ouro adequadas para a adsorção de proteínas e outros ligandos para o desenvolvimento de conjugados.

Propriedades :

as nanopartículas de ouro não conjugadas são fabricadas utilizando um protocolo exclusivo que resulta em partículas com uma distribuição de tamanho e forma superiores às do principal concorrente.

As nossas preparações de nanopartículas de ouro têm uma distribuição de tamanho estreita (CV inferior a 15%), propriedades excepcionais de adsorção de proteínas e mais de 95% de partículas esféricas. Para além disso, a baixa variabilidade de lote para lote (+/- 2nm) garante que o cliente recebe sempre um produto dentro da gama de tamanhos especificada.

Todos os nossos lotes passam por um rigoroso controlo de qualidade antes de serem enviados para os nossos clientes, utilizando a dispersão dinâmica da luz para garantir o tamanho e a monodispersão e as especificações do lote são fornecidas com cada produto.

Armazenamento:

Armazenar o produto ao abrigo da luz solar direta a 4-25°C. Uma temperatura mais baixa prolonga o prazo de validade do produto.

NÃO congelar. O congelamento provoca a agregação irreversível das nanopartículas de ouro. Quando armazenado conforme especificado, o produto é estável durante pelo menos seis meses.
