P21 peptide is a biologically active synthetic peptide mainly applied in basic laboratory research on intracellular signal transduction and cell cycle regulation. It is packed in sterile vacuum freeze-dried vials with strict low endotoxin control, suitable for cell incubation and rodent in-vivo administration experiments.

After professional freeze-drying treatment, the powder maintains complete molecular activity. It features excellent solubility, can dissolve rapidly and evenly in sterile solvent without producing turbid precipitate or insoluble residues. Strict purification and filtering processes are adopted in the whole production procedure, meeting pharmaceutical-grade production standards, which effectively guarantees stable product efficacy and safety for subsequent preparation and use.

These lyophilized peptide vials adopt standard medical transparent glass bottle design, with smooth, thickened glass walls that deliver excellent light transmission and air tightness. The bottle body is slender and neat, with uniform thickness, sturdy and shatter-resistant for daily transport and storage.
We offer multiple color options for aluminum plastic caps: yellow, blue, purple, red, white, gold and other lids for your selection. Each cap is tightly crimped with matched butyl rubber stoppers inside, effectively isolating moisture, oxygen and external pollutants to lock the purity and activity of internal white lyophilized powder.
Empty vials can be customized with printed labels, clearly marking product name, specification and batch information. For bulk storage, we supply matched transparent plastic trays with separate slots to fix each vial firmly, avoiding scratches, collision and breakage during stacking and delivery. Both single loose bottles and tray-packed sets are available to fit sample test and mass wholesale demands.
