FAQ

What is the recommended concentration for cell culture media?

Typical usage ranges from 0.5 g L⁻¹ to 2 g L⁻¹ depending on the cell line and desired growth rate. Start with 1 g L⁻¹ and adjust based on observed cell density and viability.

Is the product sterile?

The product is supplied in a sealed, sterile container. While it is free from microbial contamination, we recommend filter‑sterilizing the solution if your protocol requires a completely sterile environment.

Can I use this enzyme for protein purification buffers?

Yes, the casein peptone/tryptone blend can be added to purification buffers to stabilize proteins and reduce aggregation, especially during high‑salt or low‑pH steps.

How does the nitrogen content compare to other peptone products?

With total nitrogen exceeding 10% and amino nitrogen above 2.5%, this product offers a higher nitrogen density than many standard peptones, translating to more efficient nutrient delivery and potentially higher yields.

What storage conditions are recommended?

Store the container at 2–8 °C in a dry place. Avoid exposure to direct sunlight or moisture, which could affect stability over long periods.
