Instructions for use:
- The intended users are IVF professionals (lab technicians, embryologists or medical doctors).
- Ensure all media are well mixed before use. We strongly advice to read through all the steps of the vitrification/warming procedure before starting the procedure.
- In a 4-well dish fill the first well with 300 μl of VitriStore Pre-vitrification Medium, the second with VitriStore Freeze Medium 1 and the third with VitriStore Freeze Medium 2. Next open as many packs of vitrification devices as will be required for the vitrification step. Conveniently place the separate parts of the vitrification device on the workbench for easy access later in the procedure.
Transfer the embryos from the blastocyst cell culture medium into each of the VitriStore Freeze solutions using the following scheme:
|Stage||VitriStore Pre-vitrification||VitriStore Freeze 1||VitriStore Freeze 2||Temperature|
|Early Blastocyst, Morulae||2 min.||2 min.||30 s.||Room
|2 min.||3 min.||30 s.||37°C|
+ artificial shrinkage*
|2 min.||2 min.||30 s.||Room
*Before starting the vitrification procedure, in order to reduce the negative effect of the blastocoel, expanded blastocysts should be collapsed by reducing artificially with a glass pipette the volume of the blastocoel. (Vanderzwalmen et. al., 2002; Sonet al., 2003; Hiraoka, 2004)
- Using an attenuated pipette or an equally suitable device, deposit maximum 2 blastocysts in a volume of approximately 0.3 μl of VitriStore Freeze 2 in the gutter of the tip of the vitrification straw.
- Place the vitrification straw in the outer sheath and seal it as indicated in the instructions for use of the vitrification device.
- Plunge the sealed device into the liquid nitrogen.
- Remove the vitrification straw from the outer sheath as indicated in the instructions for use of the vitrification device.
- Immediately plunge the vitrification straw into pre-heated VitriStore Thaw Medium 1 (37°C) and leave in Thawing 1 Medium for 3 minutes.
- Transfer into VitriStore Thaw Medium 2 (37°C) and leave in this medium for 2 minutes.
- Transfer into VitriStore Thaw Medium 3 (37°C) and leave in this medium for 2 minutes.
- Finally transfer into VitriStore Thaw Medium 4 (37°C) and wash for at least 1 minute.
- Transfer into blastocyst culture medium for continued cell culture.
GM501 VitriStore Freeze/VitriStore Thaw and Embryoculture:
- GM501 VitriStore Freeze/VitriStore Thaw can be used in combination with GM501 Media (Washing- and IVF-Media) before freezing and after thawing.
Precautions and warnings:
- Standard measures to prevent infections resulting from the use of medicinal products prepared from human blood or plasma include selection of donors, screening of individual donations and plasma pools for specific markers of infection and the inclusion of effective manufacturing steps for the inactivation/removal of viruses. Despite this, when medicinal products prepared from human blood or plasma are administered, the possibility of transmitting infective agents cannot totally be excluded. This also applies to unknown or emerging viruses and other pathogens. There are no reports of proven virus transmissions with albumin, manufactured to European Pharmacopoeia specifications by established processes.
- Therefore, handle all specimens as if capable of transmitting HIV or hepatitis. Always wear protective clothing when handling specimens.
- Always work under strict hygienic conditions (LAF-bench ISO Class 5) to avoid possible contamination.
- Only for the intended use.
- The long term safety of embryo vitrification on children born following this procedure is unknown.
- Do not use the product if seal of the container is opened or defect when the product is delivered.
- Do not use the product if it becomes discoloured, cloudy or shows any evidence of microbial contamination.
