Premium PBS pH 7.4 - Cell Culture Grade

Ultra-pure PBS pH 7.4 meets stringent cell culture requirements supporting stem cell maintenance, primary cell isolation, and functional assay development across research laboratories.

Stem cell laboratories wash hESC/iPSC cultures using endotoxin-free PBS preventing differentiation. Calcium/magnesium-free formulation facilitates passaging while physiological osmolarity maintains pluripotency marker expression.

Primary cell isolation laboratories suspend hepatocytes, neurons, and cardiomyocytes in premium PBS. Protein-free specification prevents carrier effect artifacts while low endotoxin prevents TLR activation compromising functional studies.

Functional assay development laboratories standardize PBS diluents across cytokine, chemokine, and growth factor panels. Guaranteed low endotoxin prevents false positive activation compromising EC50 determination accuracy.

Quality control certificates document endotoxin (<0.03 EU/mL), protein (<1 pg/mL), and mycoplasma absence. 0.1μm sterile filtration exceeds pharmacopeial requirements supporting primary cell applications.

No animal-derived components prevent BSE/TSE transmission risks. DNase/RNase-free certification supports single-cell RNA-seq applications requiring ultra-pure buffers.

Cryopreservation protocols employ premium PBS maintaining cell viability during freeze-thaw cycles. Glycerol-compatible formulation prevents osmotic shock compromising post-thaw recovery and functionality.

ISO 13485 cGMP manufacturing utilizes USP WFI and verified cleanroom production. LAL testing by gel-clot and kinetic turbidimetric methods confirms endotoxin specifications across production lots.
