Ingredients: This product contains hyaluronidase enzyme at the rate of 80 IU/ml in a medium containing bicarbonate buffer, HEPES and human serum albumin (HSA).


The following protocol has been demonstrated to be effective for denudation of human cumulus-oocyte masses (COCs) and is provided as an example only:

1- The hyaluronidase medium is heated to a temperature of 37 degrees Celsius.
2- A dish containing one drop of 100 microliters of hyaluronidase and three to five drops of 100 microliters of HTF medium with HEPES buffer is prepared for egg washing and mineral oil is added to cover the drops completely.
3- A maximum of five cumulus-egg masses are placed in the hyaluronidase drop and repeated pipetting is done by a pipette with a suitable diameter until a part of the cumulus cell mass is separated (maximum 60 seconds).
4- Using a pipette with a suitable diameter, transfer the existing mass to the first drop of HTF medium containing HEPES buffer.
5- Corona radiata cells should be removed by repeated egg pipetting.
