Overview
Soy Peptone E110 is a soy-derived peptone, used as a nitrogen and growth-factor source in culture media. Contains soy allergen. Supplied by STBIO MEDIA with a COA for every batch; samples and specifications are available on request.
How soy peptone grades differ
Soy peptone is enzymatically hydrolysed soy protein, the plant nitrogen source in TSB and other general formulations, and the most common replacement for meat peptones. Grades in a range differ in degree of hydrolysis (amino-to-total nitrogen ratio), molecular weight distribution, carbohydrate content and clarity: more hydrolysed grades are taken up faster and suit start-up and high-density fermentation, less hydrolysed grades carry more peptides and release nitrogen longer. For cell culture choose a grade labelled clear or ultrafiltered. Soy is a declarable allergen; non-GMO raw material is marked on the product page.

Frequently asked questions
01Can soy peptone replace tryptone?
In fermentation and routine culture it usually can, with the advantage of no milk allergen and no animal components. Do not substitute it directly in formulations where a standard method specifies tryptone (LB, the indole test), as tryptophan content and peptide profile differ and results may shift.
02Is there a Halal certified version of this product?
Yes. This is the standard version; a Halal certified version is also produced from food-grade raw materials with Halal documentation, for compliant sourcing in Malaysia, Indonesia, and the Middle East.
03How do I request a bulk quotation, and can you provide a COA?
Yes. This product is available in 25 kg. Tell us your application and volume when requesting a quotation; we reply within one working day and can supply the COA, specification sheet, and technical data sheet.
