描述 PAI Activity Assay 概述 The CHEMICON PAI Activity Assay Kit provides a quick, efficient and sensitive system for evaluation of inhibition of uPA activity by PAI and for screening of uPA inhibitors. The assay is colorimetric and does not require radioactivity or fluorescence equipment. The assay is sensitive over an inhibition range of 0.05-50 units of uPA activity.
The CHEMICON PAI Activity Assay Kit utilizes a chromogenic substrate, which is cleaved by active uPA, detectable by its Optical Density at 405nm (OD405). Addition of PAI sample blocks the cleavage of substrate by uPA.
The CHEMICON PAI Assay Kit is ideal for measurement of PAI inhibitory activity toward uPA in purified preparations and cell culture, as well as in serum where pathological conditions such as sepsis exist. The assay is also useful for screening inhibitors of uPA.
Each CHEMICON PAI Activity Assay Kit contains sufficient reagents for the evaluation of 96 samples, including uPA standard from human urine and E.Coli-expressed recombinant protein corresponding to amino acids 24 to 427 of human PAI-1 (mature form) as positive control. PAI-1 positive control contains a mixture of the active and latent forms, with > 45% of active form. Duplicate or triplicate samples are suggested.
The CHEMICON PAI Activity Assay Kit is intended for research use only; not for diagnostic or therapeutic applications.

生物信息 品种反应性 Human Entrez基因编号 - NM_002658.2
Entrez基因汇总 This gene encodes a serine protease involved in degradation of the extracellular matrix and possibly tumor cell migration and proliferation. A specific polymorphism in this gene may be associated with late-onset Alzheimer disease and also with decreased affinity for fibrin-binding. The protein encoded by this gene converts plasminogen to plasmin by specific cleavage of an Arg-Val bond in plasminogen. This gene's proprotein is cleaved at a Lys-Ile bond by plasmin to form a two-chain derivative in which a single disulfide bond connects the amino-terminal A-chain to the catalytically active, carboxy-terminal B-chain. This two-chain derivative is also called HMW-uPA (high molecular weight uPA). HMW-uPA can be further processed into LMW-uPA (low molecular weight uPA) by cleavage of chain A into a short chain A (A1) and an amino-terminal fragment. LMW-uPA is proteolytically active but does not bind to the uPA receptor. 基因符号 - Urokinase-type plasminogen activator chain B].

UniProt编号 - P00749
UniProt汇总 FUNCTION: SwissProt: P00749 # Specifically cleave the zymogen plasminogen to form the active enzyme plasmin.
SIZE: 431 amino acids; 48525 Da
SUBUNIT: Found in high and low molecular mass forms. Each consists of two chains, A and B. The high molecular mass form contains a long chain A which is cleaved to yield a short chain A. Binds LRP1B; binding is followed by internalization and degradation. Interacts with MRC2. Interacts with PLAUR.
SUBCELLULAR LOCATION: Secreted.
TISSUE SPECIFICITY: Expressed in the prostate gland and prostate cancers.
PTM: Phosphorylation of Ser-158 and Ser-323 abolishes proadhesive ability but does not interfere with receptor binding.
SIMILARITY: SwissProt: P00749 ## Belongs to the peptidase S1 family. & Contains 1 EGF-like domain. & Contains 1 kringle domain. & Contains 1 peptidase S1 domain.产品使用声明 使用声明 - Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals.
