Gradient Series
A unique and novel sperm preparation portfolio


ORIGIO Gradient Series

  • Our media have a more alkaline pH to mimic the physiological conditions sperm will encounter in vivo

  • Sperm are quite sensitive to acidic external pH, which will lower the intracellular pH (pHi) in the sperm cells and thus impede sperm motility and function and alkaline (high pH) external pH stimulates several sperm motility parameters

ORIGIO Sperm Wash

for sperm preparation by swim up

ORIGIO Gradients

for efficient separation of motile sperm


ORIGIO Gradient Series

  • Bicarbonate-rich formula enhances sperm progressive motility

  • pH 8.0-8.5 to mimic in vivo physiological conditions

  • High HSA concentration to support optimal sperm function

  • Antioxidants protect spermatozoa from oxidative damage

  • HEPES buffered for use outside CO2 environment

  • Osmolality differentiated for sperm protection during isolation

  • Can be used for IUI, IVF, and ICSI

  • Shelf life after opening: 28 days
