The Amicase® (product A2427) and Hy-Case® SF (product C9386) are related items, but they are not exactly the same. The Amicase® is prepared to keep the inorganic ions to a minimum so it is high in total nitrogen. This is also the case for the Hy-Case® SF; however, this item is prepared to be essentially salt free (contains a maximum of 2.0% sodium chloride). The Hy-Case® SF is recommended for use as a microbiological nutrient in laboratory media and fermentations, where a mixture of highly soluble free amino acids is required. It is especially recommended when inorganic ion levels need to be kept at a minimum.

General description
Hy-Case® SF is a high-quality acid hydrolysis of casein. Casein is a rich source of amino nitrogen so on treatment with a strong acid, it gets hydrolysed, producing free amino acids and several short peptide fragments. Special processing keeps inorganic ions to a minimum, so Hy-Case® SF is virtually a high concentration of free amino acids with a minimum of salt. It is a refined grade hydrolysate with high clarity in solution and is food grade and is recommended where a mixture of highly soluble free amino acids is required. It is especially recommended when inorganic ion levels need to be kept at a minimum.
Application
Casein hydrolysate Hy-Case® SF was used in DMCY medium, during an experimental study conducted to investigate the role of ssgA gene product in promoting the sporulation and cell division in Streptomyces griseus.[1] It may also be used in the YH medium in studies related to Halobacterium denitrificans sp. which is characterised as being carbohydrate-utilizing, denitrifying, extremely halophilic bacteria.[2]
Recommended for use as a microbiological nutrient in laboratory media, fermentations, and tissue culture applications requiring a mixture of highly soluble free amino acids.
