  • For oocytes handling/incubation in preparation of, or during fertilization by in vitro fertilization (IVF)/ intra cytoplasmatic sperm injection (ICSI).
  • For embryo culture from day 1 to expanded blastocyst stage.
  • For embryo transfer (ET).

GAINTM medium is ready-to-use.

Composition

GAINTM medium is a bicarbonate-buffered balanced salt solution, supplemented with 10mg/l gentamicin (medicinal substance) and 3.5g/l human serum albumin (medicinal substance derived from human blood plasma) and phenol red.
