To complement our media development and optimization services, Irvine Scientific offers Spent Media Analysis. This analysis provides an understanding of changes in culture conditions over time. We can provide data within approximately 10 business days.
Below are descriptions of our current offerings, as well as sample preparation instructions.
| LEVEL ONE | |
| Glucose, Lactate, Glutamine, Ammonia | |
| (Nova BioAnalyzer) | |
|
These components are primary indicators of culture kinetics. |
|
| LEVEL TWO | |
| Amino Acids | |
| (HPLC with UV) | |
| Includes 20 amino acids commonly found in cell culture media. Amino acids can be rate limiting factors for both growth and production. | |
| LEVEL THREE | |
| Water Soluble Vitamins | |
| (HPLC with UV) | |
| Includes pyridoxine, Niacinamide, Folic Acid, Vitamin B12, Riboflavin and Thiamine. This testing is primarily for in-depth media development. | |
