INSTRUCTIONS FOR USE
The procedures described below have been found to be effective for the retrieval and washing of human oocytes and are offered only as examples. Every laboratory must define and optimize its own procedures.
- global® Collect® should be supplemented with Human Serum Albumin (HSA) or LifeGlobal® Protein Supplement to achieve desired % (v/v) of protein supplementation.
- Warm the protein-supplemented global® Collect® to 37°C prior to use.
