Purity

>95%, by SDS-PAGE and HPLC

Endotoxin Level

Less than 0.1 EU/ug of SerpinB2 as determined by LAL method.

Predicted Molecular Mass

46.6 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Activity

SerpinB2 protein is fully biologically active when compared to standard. The biologically active was determined by its inhibitory effect against single chain tPA induced cleavage of a chromogenic substrate in Imidazole Buffer at 37 degrees C. Half maximal inhibition against 1.0 ug/ml of single chain tPA was at a concentration of 1.0 ug/ml.

Background: Serpin B2

SerpinB2 (PAI-2) is an inhibitory serpin expressed mainly in keratinocytes, activated monocytes, and placental trophoblasts. It exists predominantly as a 47 kDa non-glycosylated intracellular protein which can be induced to be secreted as 60 kDa glycoprotein. The glycosylated and unglycosylated forms of SerpinB2 (PAI-2) are equally effective as inhibitors of urokinase-type plasminogen activator (uPA), the only established physiological target of this serpin.

Product Specific Notices for Recombinant Human SerpinB2 Protein

This lyophilized preparation is stable at 2-8 degrees C, but should be kept at -20 degrees C for long term storage, preferably desiccated. Upon reconstitution, the preparation is most stable at -20 to -80 degrees C, and can be stored for one week at 2-8 degrees C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 degrees C to -80 degrees C. Avoid repeated freeze/thaw cycles.

This product is for research use only and is not approved for use in humans or in clinical diagnosis. This product is guaranteed for 1 year from date of receipt.
