Antibiotic/Antimycotic Solution (100x)

Volume: 100 ml Storage: ≤-15°C Sterility: Sterile-filtered Antibiotic/Antimycotic Solution (100x) is a sterile, ready-to-use concentrate designed to reduce microbial contamination risks in cell culture and related laboratory applications. This 100x solution contains a well-established combination of penicillin, streptomycin, and amphotericin B—providing broad-spectrum antimicrobial activity against Gram-positive and Gram-negative bacteria, yeasts, and filamentous fungi. The formulation is suitable for use in eukaryotic cell cultures, bacterial media, and other contamination-sensitive systems, supporting clean and consistent lab operations. Application and Benefits Optimized for routine research protocols, this solution is widely used to maintain aseptic conditions in cell culture workflows. It offers reliable performance in contamination-sensitive environments, helping researchers reduce the risk of microbial overgrowth without compromising cell health or experimental reproducibility. The sterile-filtered formulation eliminates the need for additional solubilization steps, supporting streamlined media preparation and reducing variability in daily lab procedures. Usage and Compatibility To achieve standard working concentrations, dilute the solution 1:100 into your complete culture medium. The product is compatible with a broad range of mammalian cell lines and basal media. With consistent stock availability, researchers benefit from dependable supply continuity and simplified logistics planning. The solution should be stored at ≤ –15 °C and protected from repeated freeze-thaw cycles to maintain stability. For research use only. Not for use in diagnostic or therapeutic procedures. Not for use in humans or animals.

PBS

Fosfatbufferet saltvand (PBS) er en meget udbredt bufferopløsning inden for biologisk og kemisk forskning. Den spiller en afgørende rolle for opretholdelsen af pH-balancen og osmolariteten under forskellige eksperimentelle procedurer, herunder vævsbehandling og cellekultur. Vores PBS-opløsning er omhyggeligt sammensat af ingredienser med høj renhed for at sikre stabilitet og pålidelighed i hvert eneste eksperiment. Osmolariteten og ionkoncentrationerne i vores PBS svarer tæt til dem i den menneskelige krop, hvilket gør den isotonisk og ikke-toksisk for de fleste celler. Sammensætning af vores PBS-opløsning Vores PBS-opløsning er en pH-justeret blanding af fosfatbuffere i ultrarent kvalitet og saltopløsninger. Ved en 1X arbejdskoncentration indeholder den: • 8000 mg/L natriumchlorid (NaCl) • 200 mg/L Kaliumchlorid (KCl) • 1150 mg/L vandfrit dibasisk natriumphosphat (Na₂HPO₄) • 200 mg/L vandfrit monobasisk kaliumphosphat (KH₂PO₄) Denne sammensætning sikrer en optimal pH-værdi og ionbalance, der er velegnet til en bred vifte af biologiske anvendelser. Anvendelser af vores PBS-opløsning Vores PBS-opløsning er ideel til forskellige anvendelser inden for biologisk forskning. Dens isotoniske og ikke-toksiske egenskaber gør den velegnet til fortynding af stoffer og skylning af cellebeholdere. PBS-opløsninger indeholdende EDTA er effektive til at løsne fastsiddende og sammenklumpede celler. Der bør dog ikke tilsættes toværdige metaller såsom zink til PBS, da dette kan forårsage udfældning. I sådanne tilfælde anbefales Good's buffere. Derudover er vores PBS-opløsning et acceptabelt alternativ til viralt transportmedium til transport og opbevaring af RNA-vira, herunder SARS-CoV-2. Kvalitetskontrol • Sterilfiltreret Opbevaring og holdbarhed • Opbevares ved +2 °C til +25 °C, beskyttet mod lys. • Når emballagen er åbnet, skal produktet opbevares ved 2 °C til 25 °C og anvendes inden for 24 måneder. Forsendelsesbetingelser • Omgivelsestemperatur Opbevaring • Opbevares i køleskab ved +2 °C til +8 °C i mørke. Undgå frysning og hyppig opvarmning til +37 °C, da dette nedsætter produktets kvalitet. • Mediet må ikke opvarmes til over 37 °C, og der må ikke anvendes ukontrollerede varmekilder, såsom mikrobølgeovne. • Hvis kun en del af mediet skal bruges, skal den nødvendige mængde tages ud og opvarmes til stuetemperatur før brug.

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.
