This buffer is membrane-impermeable, has minimal interference with biochemical reactions, and demonstrates strong chemical and enzymatic stability. These properties make it suitable for a wide range of cell culture and biochemical applications. Formulation and Usage The solution is supplied as a 1 M concentrate prepared in cell culture–grade water and is sterile-filtered for use in contamination-sensitive environments. It can be diluted to the desired working concentration depending on application requirements. Store at +2°C to +8°C and handle under aseptic conditions to preserve product integrity. For research use only. Not for use in diagnostic or therapeutic procedures. Not for use in humans or animals.

PBS

A solução salina tamponada com fosfato (PBS) é uma solução tampão amplamente utilizada na investigação biológica e química. Desempenha um papel crucial na manutenção do equilíbrio do pH e da osmolaridade durante vários procedimentos experimentais, incluindo o processamento de tecidos e a cultura celular. A nossa solução de PBS é meticulosamente formulada com ingredientes de elevada pureza para garantir estabilidade e fiabilidade em todas as experiências. A osmolaridade e as concentrações iónicas da nossa PBS assemelham-se estreitamente às do corpo humano, tornando-a isotónica e não tóxica para a maioria das células. Composição da nossa solução de PBS A nossa solução de PBS é uma mistura com pH ajustado de tampões de fosfato de grau ultrapuro e soluções salinas. A uma concentração de trabalho de 1X, contém: • 8000 mg/L de cloreto de sódio (NaCl) • 200 mg/L de cloreto de potássio (KCl) • 1 150 mg/L de fosfato de sódio dibásico anidro (Na₂HPO₄) • 200 mg/L de fosfato de potássio monobásico anidro (KH₂PO₄) Esta composição garante um pH e um equilíbrio iónico ideais, adequados para uma vasta gama de aplicações biológicas. Aplicações da nossa solução PBS A nossa solução PBS é ideal para várias aplicações na investigação biológica. As suas propriedades isotónicas e não tóxicas tornam-na adequada para a diluição de substâncias e a lavagem de recipientes celulares. As soluções PBS que contêm EDTA são eficazes para separar células aderidas e aglomeradas. No entanto, não devem ser adicionados metais divalentes, como o zinco, à PBS, uma vez que isso pode causar precipitação. Nesses casos, recomendam-se os tampões da Good. Além disso, a nossa solução PBS é uma alternativa aceitável ao meio de transporte viral para o transporte e armazenamento de vírus de ARN, incluindo o SARS-CoV-2.

Stable Glutamin (200mM), L-Alanyl-L-Glutamine Solution

Volume: 100 ml Storage: ≤ –15°C Sterility: Sterile-filtered Stable Glutamine Solution (L-Alanyl-L-Glutamine, 200 mM) is a highly stable dipeptide form of L-glutamine designed as a direct replacement for conventional L-glutamine in cell culture media. L-glutamine is an essential amino acid and a major energy source for cultured cells, playing a critical role in cell growth, metabolism, and protein synthesis. Application and Benefits In standard liquid media, L-glutamine degrades relatively quickly at 37°C, leading to the formation of toxic byproducts such as ammonium ions that can negatively affect cell viability and experimental outcomes. Stable glutamine overcomes this limitation by providing a non-degrading dipeptide form that remains intact in culture conditions. Cells enzymatically cleave the dipeptide bond to release L-glutamine as needed, ensuring a continuous fresh supply while preventing the accumulation of harmful waste products. This makes the solution particularly advantageous for long-term cell cultures and high-density growth systems. Formulation and Usage The L-Alanyl-L-Glutamine solution is prepared in cell culture–grade water at a concentration of 200 mM and is sterile-filtered for contamination-sensitive applications. It can be diluted directly into complete media according to experimental requirements. Store at ≤ –15°C and avoid repeated freeze-thaw cycles to maintain product stability. For research use only. Not for use in diagnostic or therapeutic procedures. Not for use in humans or animals.
