GDN - Digitonin's synthetic alternative
Here are 5 reasons why you should switch to GDN
1. No risk of toxic byproducts
While digitonin is a natural product and can contain harmful byproducts such as digitoxin and digoxin, GDN is produced synthetically, without toxins.
2. No batch-to-batch variation
Again, as a synthetic product, GDN has the benefit of not varying between batches as digitonin does.
3. Lower CMC
GDN's critical micelle concentration is 18uM - way lower than digitonin's 0.25-0.5 mM!
4. Better water solubility
With ≥10% water-solubility at RT, GDN beats digitonin even here!
5. It’s cheaper!
For example, 500mg GDN costs CHF 168.- vs. over 300.- for digitonin!
At LubioScience, we offer Anatrace’s high-quality GDN101 (≥98% purity by HPLC analysis) in multiple sizes between 500 mg and 100 g
As we have this product in stock (5g size GDN1015GM), we can offer it at 24h delivery for customers in Switzerland.
