Product Description
Leibovitz's L-15 Medium, no phenol red
Description
Leibovitz's L-15 Medium supports the growth of HEP-2 monkey kidney cells and primary explants of embryonic and adult human tissue. L-15 is buffered by phosphates and free base amino acids instead of sodium bicarbonate. This medium is designed for supporting cell growth in environments without CO
2 equilibration.
This L-15 is modified as follows:| With | Without |
| Galactose | Glucose |
| L-glutamine | Phenol Red |
| Sodium Pyruvate | HEPES |
The complete formulation is available.
Using L-15L-15 contains no proteins, lipids, or growth factors. Therefore, L-15 requires supplementation, commonly with 10% Fetal Bovine Serum (FBS).
cGMP manufacturing and quality systemLeibovitz's L-15 Medium is manufactured at a cGMP-compliant facility located in Grand Island, New York. The facility is registered with the FDA as a medical device manufacturer and is certified to ISO 13485 standards.
