MEM Alpha Medium, Powder, without L-glutamine, phenol red，210-011

We confirm the quality of our Powdered Classical Basal Media by evaluating samples from each batch as required by specifications. Samples are prepared as 1× liquid form, and membrane filtration is performed; testing may include endotoxin level, solubility, osmolality, and pH. The values for these parameters are determined using the test conditions described for Powdered Classical Basal Media, and this medium is formulated without sodium bicarbonate to enhance stability.
