BBL Phytone Peptone<br />

Difco Select Phytone UF<br />

Difco Select Soytone<br />

Bacto Soytone<br />

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 />
