Product Description<br />
All the Difco and BBL brand soy peptones are enzymatic digests of soybean meal/flour. They<br />
are recommended for use in media for the cultivation of a wide variety of organisms, including<br />
fungi. The soybean protein in these peptones contains naturally occurring high concentrations<br />
of vitamins and carbohydrates.<br />
Potential Applications<br />
<strong>BD</strong> offers a diverse choice of soy peptones. The individual characteristics of each peptone are<br />
the result of processing methods engineered to consistently deliver these characteristics from<br />
batch to batch. The nutritional requirements of microorganisms and cell lines vary according<br />
to each individual strain. While some organisms or cell lines may prefer short chain or free<br />
amino acids, others benefit from longer chain amino acids. While the typical analysis profiles<br />
for each peptone in this manual can help direct the end-user to the correct peptone match,<br />
it is recommended that end-users supplement the typical analytical information with<br />
evaluations in their own individual growth models.<br />
Select Phytone UF is an ultrafiltered peptone that was developed specifically for the tissue<br />
culture market. Its nitrogen content combined with the naturally occurring vitamins has<br />
demonstrated remarkable growth support with monoclonal antibodies and protein expression.<br />
It has an endotoxin level of less than or equal to 500 EU/g.<br />
<strong>BD</strong> offers three other soy peptone products suitable for a variety of bacterial cultures.<br />
