HSP429 is a highly filtered papaic digest of soy, designed for use in diagnostic media and microbial fermentations. HSP429 can assist in high levels of recovery of difficult to grow organisms, and will also allow high cell yield in fermentation broths for many organisms. HSP429 has a high level of clarity and is heat-stable.

HSP349 is a highly filtered papaic digest of soy designed for use in diagnostic media and microbial fermentations. HSP349 has high clarity levels and is heat stable.

HSP320 is a highly filtered enzymatic digest of soy with an elevated degree of hydrolysis. HSP320 is rich in free amino acids and small peptides which are an excellent source of readily available nitrogen. HSP320 has high clarity levels and is heat stable.

HCP512 is a casein peptone that has been specially designed for use in microbial fermentation applications. HCP512 is heat stable and clear in solution.
