Vitrification Kit 101

Contents of Cryotech Vitrification Kit 101”

  • Equilibration Solution (ES): 1 vial of 1.0ml.
  • Vitrification Solution (VS): 2 vials of 1.0ml.
  • 4 Cryotecs: 1 Cryotec can contain more than one oocyte/embryo (recommend 3-4 maximum for oocytes and 4-cell embryos and one for blastocyst for single embryo transfer).
  • -3 Vitri Plates with 3 wells each.

Guidelines to use Cryotech Vitrification Kit 101”

  • -Room temperature (25–27ºC) should be used for the entire process.
  • -Pour nitrogen into a container.
  • -Make a note of the thickness of the oocyte and compare it to the periviteline space in the zona pellucida.
  • It’s crucial to use a Pasteur pipette with the appropriate diameter for both blastocysts (160-200 µm) and oocyte embryos (140-150 µm).

Equilibration of oocytes and embryos

  1. Transfer 300 µl of ES into each of the 1º, 2º, and 3º wells on the Vitri Plate.
  2. Place the oocyte/embryo in the 1½ well on the ES surface.
  3. The embryo or oocyte will sink and start to shrink back to its initial size (blastocysts and oocytes can take up to 15 minutes, and other stages of the embryo can take up to 12 minutes).

    Vitrification Protocol

    Please take note: You have 25 seconds to complete the following steps, with a maximum of 90 seconds.

  4. Use VS to transfer the oocyte or embryo to the bottom of the 2° well (Instead of starting with a minimum volume of ES.) The oocyte/embryo washes up and instantly floats to the surface of VS.
  5. Take just the oocyte or embryo and place it in the bottom of the well after cleaning the pipette’s interior wall with new VS media. Hold off until the embryo/oocyte stops floating in VS.
  6. Place the oocyte or embryo in the center of the 3° well with VS, and use a pipette to mix the media five times.
  7. Using the pipette, remove only the oocyte or embryo at the tip, and place it on the end of the cryotec seat with the least amount of VS.
  8. Drop the Cryotech into liquid nitrogen right away.
  9. Insert the cap and keep it in a nitrogen tank for storage.
