Culture media

After formulation culture media are tested for quality control followed by sterilization by filtration and storing in sterile containers.

Batches accepted must fulfill these parameters:

  Natur ARTs PIG-Swim Up Medium
pH 7.4-7.8
Osmolarity (mOsm/kg) 320-340
Endotoxin (EU/mL) <0.15
Sterility No growth
Sperm count (millions/mL) after swim-up*  
fresh ejaculated pig spermatozoa >1
frozen-thawed pig spermatozoa >5

*Following the instructions provided in MSDS. The rate can vary depending of the quality in the original seminal sample.

Sterility No growth No growth
Bovine Embryo Assay (BEA) >80% cleavage rate >25% blastocyst formation
Porcine Embryo Assay (PEA) >70% cleavage rate >20% blastocyst formation
