Trypsin Inhibitor from Soybean, CAS No.9035-81-8

CAS: 9035-81-8 Cat. No.: S752084 Numero EC: 232-906-9

GRADE & PURITY ActiBioPure™, Native, for Cell culture, ≥0.7mg Trypsin/mg Inhibitor (Trypsin activity is about 10000 BAEE units/mg)

Accession #

P01070

Bioactivity

≥0.7mg Trypsin/mg Inhibitor (Trypsin activity is about 10000 BAEE units/mg)

Panoramica

  This product is a natural active protein extracted from non-genetically modified soybeans, containing only the Kunitz Trypsin Inhibitor (KTI) protein component. It has trypsin inhibitor activity but no chymotrypsin (also known as chymase) inhibitor activity. The trypsin inhibitor (Trypsin Inhibitor, TI) activity of this product is ≥10000 BAEE U/mg, and it has high purity, making it suitable for experiments such as biochemical detection and cell culture.

Soybean protease inhibitors include two types of trypsin inhibitors: Bowman-Birk Inhibitor (BBI) and Kunitz Trypsin Inhibitor (KTI). BBI is a protein with a molecular weight of about 8KD Daltons, which has the property of inhibiting trypsin and chymotrypsin; KTI is a protein with a molecular weight of about 23KD Daltons, which has the property of inhibiting trypsin and is a stable globulin-type protein.

What is ActiBioPure??

ActiBioPure? is one of Aladdin Scientific's premium product lines, formulated for high-purity applications across multiple workflows. Compared to standard grades in the same workflow, ActiBioPure? products typically offer tighter specifications, more rigorous QC, and stronger lot-to-lot consistency.

What does Native mean?

Native indicates that the material has been processed and tested for specialty industrial processing. Specifications focus on the impurities that affect performance in that application — for example, metal content for electronics, particle size for batteries, refractive index for optics, or moisture content for moisture-sensitive processes.

How should this product be stored?

Store at 2–8 °C. Refrigerated storage is required to maintain the specified shelf life.

How is this product shipped?

This product ships chilled on wet ice. Unpack on arrival and transfer it to the storage condition stated above.

What are the CAS number, molecular formula and molecular weight?

The CAS Number is 9035-81-8.
