What reagent grades, purity labels and specifications mean: ACS/AR, HPLC, electronic grade and tag-grade proteins, in 190+ guides from Aladdin Scientific.
LC–MS/MS–based proteomics has expanded from discovery research to quantitation, multi-site PTM profiling, targeted verification, and large-cohort studies. Compared with routine protein experiments, proteomics is more sensitive to chemical background, ion suppression, sample loss, and batch ...
Flow cytometry analyzes cells at the single-cell level and, with multi-laser/multi-channel fluorescence detection, can rapidly measure high-dimensional cell phenotypes, functions, and microenvironments.
In cell culture, single-use compounding systems, IVD components, and sterile tooling, terminal sterilization is often used as one of the risk-control measures.
These solvents/reagents are manufactured and QC-tested specifically for ultra-high-performance LC (sub-2 µm particles, high pressure) with mass-spectrometry detection. They have very low non-volatile residue, ppb-level metals, minimal UV/MS background, and sub-micron particulates so columns and ...
SDS-PAGE endows proteins with approximately uniform charge density under denaturing conditions via sodium dodecyl sulfate and separates them by apparent molecular weight through the gel’s sieving effect. It is a foundational technique for protein identification, purity assessment, and quality ...
Immunohistochemistry (IHC) integrates tissue morphology with immunology to visualize target molecule expression on tissue sections via antigen–antibody specific recognition. It is widely used in basic research, drug development, pathological validation, and digital pathology analysis. IHC is ...
Basic-Grade Reagents, also known as Laboratory Grade, Practical Grade, or Chemically Pure (CP), are chemicals that meet a manufacturer’s internal specifications for purity. They are intended for applications where high precision and the absence of trace impurities are not critical to the ...
“For atomic absorption spectroscopy” (often shown as AAS grade) identifies reagents and standards formulated so their trace metal background is extremely low and lot-to-lot composition is tightly controlled—so blanks stay quiet and calibration stays linear at ppb–ppt levels.
Chemiluminescence (CL) is a highly sensitive detection technique in which chemical reaction energy is converted into light, and it is widely used in immunoassays, nucleic-acid tests, enzyme-activity measurements, and clinical diagnostics.
