HEPES Buffer Solution (1M)

Volume: 100 ml Storage: +2°C to +8°C Sterility: Sterile-filtered HEPES Buffer Solution (1 M), also known as N-2-hydroxyethylpiperazine-N-2-ethanesulfonic acid, is a zwitterionic organic buffering agent widely used in cell culture media. It is designed to maintain stable pH conditions in the physiological range of 6.7 to 8.6, supporting optimal cellular function during in vitro applications. Application and Benefits HEPES provides reliable buffering capacity in cell culture systems, particularly when cells are handled outside a CO₂ incubator. The addition of 10–25 mM HEPES to culture media offers enhanced pH stability during extended manipulation periods, helping to maintain consistent experimental conditions. 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

La solution saline tamponnée au phosphate (PBS) est une solution tampon largement utilisée dans la recherche biologique et chimique. Elle joue un rôle crucial dans le maintien de l'équilibre du pH et de l'osmolarité au cours de diverses procédures expérimentales, notamment le traitement des tissus et la culture cellulaire. Notre solution PBS est méticuleusement formulée à partir d'ingrédients de haute pureté afin de garantir stabilité et fiabilité dans chaque expérience. L'osmolarité et les concentrations ioniques de notre PBS reproduisent fidèlement celles du corps humain, ce qui la rend isotonique et non toxique pour la plupart des cellules. Composition de notre solution PBS Notre solution PBS est un mélange, dont le pH a été ajusté, de tampons phosphatés de qualité ultra-pure et de solutions salines. À une concentration d’utilisation de 1X, elle contient : • 8 000 mg/L de chlorure de sodium (NaCl) • 200 mg/L de chlorure de potassium (KCl) • 1 150 mg/L de phosphate de sodium dibasique anhydre (Na₂HPO₄) • 200 mg/L de phosphate de potassium monobasique anhydre (KH₂PO₄) Cette composition garantit un pH et un équilibre ionique optimaux, adaptés à un large éventail d'applications biologiques. Applications de notre solution PBS Notre solution PBS est idéale pour diverses applications dans la recherche biologique. Ses propriétés isotoniques et non toxiques la rendent adaptée à la dilution de substances et au rinçage des récipients à cellules. Les solutions PBS contenant de l'EDTA sont efficaces pour détacher les cellules adhérentes et agglomérées. Cependant, les métaux divalents tels que le zinc ne doivent pas être ajoutés au PBS, car cela peut provoquer une précipitation. Dans de tels cas, les tampons Good's sont recommandés. De plus, notre solution PBS constitue une alternative acceptable au milieu de transport viral pour le transport et le stockage des virus à ARN, y compris le SARS-CoV-2. Contrôle qualité • Filtré stérile Conservation et durée de conservation • Conserver entre +2 °C et +25 °C, à l'abri de la lumière. • Une fois ouvert, conserver entre 2 °C et 25 °C et utiliser dans les 24 mois. Conditions d'expédition • Température ambiante Conservation • Conserver au réfrigérateur entre +2 °C et +8 °C, à l'abri de la lumière. Éviter le gel et les réchauffements fréquents à +37 °C, car cela réduit la qualité du produit. • Ne pas chauffer le milieu au-delà de 37 °C ni utiliser de sources de chaleur non contrôlées telles que les fours à micro-ondes. • Si seule une partie du milieu doit être utilisée, prélevez la quantité nécessaire et réchauffez-la à température ambiante avant utilisation.

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.
