Wondering about the right PPM™ ratio for your tissue culture setup? 🔬 For Beginners: If you’re new to tissue culture or don’t have access to a laminar flow hood, it’s safer to use a higher concentration of PPM™. Start with 3-4 milliliters per liter to ensure your cultures stay free from contamination. This higher dose helps compensate for less controlled environments. 🧑‍🔬 For Experienced Culturists: With experience and proper equipment like a laminar flow hood, you can reduce the PPM™ dosage.
