Cell Biology Product Documentation

Documentation for Solarbio cell biology reagents including cell culture media and supplements, apoptosis detection, cell proliferation assays, and staining products.

Scope

Solarbio cell biology products support mammalian cell culture, cell function analysis, and cell-based assays for academic research, drug discovery, and clinical translational studies. All products are manufactured in ISO 9001:2015 certified facilities with lot-specific quality control data.

Why Choose Solarbio Cell Biology Products

  • All cell culture reagents tested for endotoxin (<0.5 EU/mL), sterility, and pH
  • Apoptosis and proliferation kits validated on multiple cell lines (HeLa, HEK293, Jurkat, HepG2)
  • Fluorescent dyes supplied with lot-specific absorption/emission spectra
  • Competitive pricing: typically 40% below Thermo Fisher or BD Biosciences equivalents
  • Technical protocols optimized for commonly used instruments (flow cytometers, plate readers, fluorescence microscopes)
  • Extended shelf life: 12–24 months depending on product category

Quality Control Testing

Each lot of cell biology reagent undergoes:

  • Cell culture media: Sterility testing (USP <71>), endotoxin (LAL assay), pH verification at 37°C, osmolality measurement, and cell growth promotion testing (at least 5 population doublings over 72 h on HeLa cells)
  • Apoptosis kits: Validation on Jurkat cells treated with 0.5 µM staurosporine; >95% apoptotic discrimination confirmed by flow cytometry
  • Proliferation assays: Linearity verified across 500–50,000 cells/well using HeLa cells; signal-to-noise ratio >10:1 confirmed
  • Cell staining reagents: Lot-specific absorption spectra confirmed by UV-Vis spectrophotometry; tissue section staining patterns verified on control slides
