Hplc grade solvents water and acetonitrile

Manufactured by Thermo Fisher Scientific
Sourced in United States

HPLC grade solvents, including water and acetonitrile, are high-purity solvents specifically designed for use in high-performance liquid chromatography (HPLC) applications. These solvents are carefully filtered and processed to minimize impurities, ensuring consistent and reliable performance in HPLC systems.

Quantifying Unreacted Soluble Protein

Check if the same lab product or an alternative is used in the 5 most similar protocols
Quantification of unreacted soluble protein in the aggregation mixture was followed by periodically removing aliquots (~80 μL) from ongoing aggregation reactions followed by centrifugation at 160,000×g and injecting the supernatant (approx. 20 μL) in duplicates into an analytical reverse phase column (Agilent Zorbax-C8 2.5 × 50 mm column). Protein samples were run against a gradient of acetonitrile (0–100%) in 0.1% TFA maintained at 300 μL·min-1 flow rate in an Agilent HPLC system (1100 series). The wavelength of the UV detector was fixed at 280 nm. HPLC grade solvents (Water and Acetonitrile) used as mobile phase in the reverse phase HPLC system were obtained from Fisher Chemicals. Concentration of the unreacted soluble protein was determined from integrated A280 nm peaks using standard curves individually acquired for each protein.37

Synthesis and Characterization of MCPF-Gly and MCPA-Gly Standards

Check if the same lab product or an alternative is used in the 5 most similar protocols
Custom synthesis of isotopically-labeled and unlabeled MCPF-Gly and MCPA-Gly standards was contracted from IsoSciences, LLC (King of Prussia, PA). Label sites for isotopically-labeled standards are indicated by asterisks in Scheme 1. The purity of the unlabeled standards is ≥97%, and the isotopic incorporation of isotopically-labeled standards is ≥99.3%. HPLC grade solvents acetonitrile and water were obtained from Fisher Scientific (Pittsburgh, PA, USA). Formic Acid (98% purity) was obtained from Sigma Chemical Company (St. Louis, MO). Pooled human urine matrix used for calibrators and quality control (QC) materials was obtained commercially from Tennessee Blood Services (Memphis, TN, USA). The urine products used for calibrators, quality control materials, and the convenience set of 96 individual urine samples were acquired from commercial sources, and the work did not meet the definition of human subjects as specified in 45 CFR 46.102 (f).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
