Applications
Where this SKU is used in research workflows.
Ex-vivo tissue rinsing
Rinse explants, biopsies, and ex-vivo tissues without inducing osmotic stress that would compromise tissue architecture or downstream histology.
Isotonic stock dilution
Dilute concentrated peptide or protein stocks to a working concentration where pure water would lyse cells via osmotic shock.
Cell suspension wash
Wash cell suspensions between centrifugation steps in workflows where serum-containing buffers would interfere with downstream assays.

Common questions
About this product.
What is the osmolarity of 0.9% saline?
Approximately 308 mOsm/L, which matches the osmolarity of mammalian extracellular fluid (≈290–300 mOsm/L). This is what makes 0.9% NaCl "isotonic" and why pure water would cause hypotonic lysis if applied directly to cells.
Can I use it as a vehicle control for hydrophobic compounds?
Only if the compound is soluble in saline at your working concentration. Many hydrophobic peptides require a co-solvent (DMSO, ethanol, or acetic acid) for stock preparation; in those cases, your vehicle control should match the final co-solvent percentage in saline.
Is this preservative-free?
Yes. This SKU is preservative-free. For workflows that require multi-draw use over an extended period and where preservative is acceptable, contact us about bacteriostatic saline alternatives.
How do I download the Certificate of Analysis?
