Product Description


Liquid Alkaline Protease JP-300

Proteolytic Enzyme for Leather and Silk

Halal and Kosher Certificate


Alkaline protease JP-300 is produced from Bacillus subtilis through submerged fermentation, extraction and refining process. JP-300 can catalyze the hydrolysis of proteins under alkaline conditions. It is suitable for leather making and silk degumming.

Product Characteristics

Declared Enzyme: Protease Systematic Name: EC Appearance: Pale brown liquid Activity: 300,000 U/ml(Minimum) Density: ≤1.25 g/ml *Definition of enzyme activity unit: One Unit of enzyme activity of protease, expressed in U/ml, is defined as one μg tyrosine released from casein per minute during proteolysis by one milliliter protease liquid at 40±0.2 ℃ and pH 10.5.


JP-300 can work at pH from 6 to 11 with its optimal pH from 5 to 10.


JP-300 can work from 20 to 60℃with its optimal temperature ranges from 30 to 45℃.


JP-300 can be activated by Ca2+, Mn2+, Mg2+, Zn2+, Fe2+ and remain un-sensitive to EDTA, sulfur reagents and heavy metals. Reagents that react with serine, such as sulfonyl halide, can lead to inactivation of JP-300.


Use of JP-300 enables the following benefits for leather processing:

1  Simplified process
2 Shortened processing cycle
3  Improved quality of finished products
4  Increased leather yields
5  Reduced production costs




Liquid Alkaline Protease JP-300 Proteolytic Enzyme For Leather And Silk 0


Use of JP-300 enables the following benefits for silk degumming:

1 Effectively removal of silk sericin without damage to the fibroin
2 Enable silk fleeciness and lustrous, soft and smooth surface

Liquid Alkaline Protease JP-300 Proteolytic Enzyme For Leather And Silk 1SAFETY & ENZYME HANDLING

Inhalation of enzyme dust and mists should be avoided. In case of contact with skins or eyes, promptly rinse with water for at least 15 minutes. For detailed handling information, please refer to the Safety Data Sheet.



1. JP-300 is packaged in 25kg, 30kgHDPE drums or 1125 kg IBC totes. Customized packaging is also available upon request.

2. Typical shelf-life is six months provided it is stored 0 to 10°C in its original packaging, sealed and unopened, protected from direct sunlight.

3. JP-300 has been formulated for optimal stability. Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement, therefore should be avoided.
