Homogeneous suspension
CMC-NA
≥5mg/ml Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 Leupeptin Hemisulfate is a reversible inhibitor of serine and cysteine proteases. It inhibits cathepsin B (Ki = 6 nM), calpain (Ki = 10 nM), trypsin (Ki = 35 nM), plasmin (Ki = 3.4 μM), and kallikrein (Ki = 19 μM), and has no effect against chymotrypsin, elastase, renin, or pepsin.
in vitro

Leupeptin, produced by various species of actinomycetes, strongly inhibit proteolysis. [1]

Leupeptin hemisulfate protects tubulin from endogenous proteolytic activities during the isolation procedure and results in increased tubulin purity. [2]

Leupeptin hemisulfate could restore up to 50% of hepatitis B surface antigen (HBsAg) expression in cell suspension cultures. [3]
