PBS

Fosfatbuffert saltvann (PBS) er en mye brukt bufferløsning innen biologisk og kjemisk forskning. Den spiller en avgjørende rolle for å opprettholde pH-balansen og osmolariteten under ulike eksperimentelle prosedyrer, blant annet vevsbehandling og cellekultur. Vår PBS-løsning er nøye sammensatt av ingredienser med høy renhet for å sikre stabilitet og pålitelighet i hvert eksperiment. Osmolariteten og ionekonsentrasjonene i vår PBS ligner i stor grad på de i menneskekroppen, noe som gjør den isotonisk og ikke-toksisk for de fleste celler. Sammensetning av vår PBS-løsning Vår PBS-løsning er en pH-justert blanding av fosfatbuffere og saltløsninger av ultrarent kvalitet. Ved en 1X arbeidskonsentrasjon inneholder den: • 8000 mg/L natriumklorid (NaCl) • 200 mg/L kaliumklorid (KCl) • 1150 mg/L vannfritt dibasisk natriumfosfat (Na₂HPO₄) • 200 mg/L vannfritt monobasisk kaliumfosfat (KH₂PO₄) Denne sammensetningen sikrer en optimal pH-verdi og ionebalanse, egnet for et bredt spekter av biologiske anvendelser. Anvendelser av vår PBS-løsning Vår PBS-løsning er ideell for ulike anvendelser innen biologisk forskning. Dens isotoniske og giftfrie egenskaper gjør den egnet til fortynning av stoffer og skylling av cellebeholdere. PBS-løsninger som inneholder EDTA er effektive for å løsne fastsittende og sammenklumpede celler. Imidlertid bør ikke toverdige metaller som sink tilsettes PBS, da dette kan føre til utfelling. I slike tilfeller anbefales Good's buffere. I tillegg er vår PBS-løsning et akseptabelt alternativ til viralt transportmedium for transport og lagring av RNA-virus, inkludert 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.
