This assay recognizes natural active human PAI-1. Pooled normal plasma from Sheep was assayed, and no significant cross-reactivity was observed. Pooled normal plasma from Mouse resulted in significant color development. The following factors were tested for cross-reactivity.
Complete Kit
Human plasma
The minimum detectable dose (MDD) was determined by adding two standard deviations to the mean optical density value of twenty zero standard replicates (range OD450: 0.161-0.178) and calculating the corresponding concentration. The MDD was 0.385 U/ml.
Intra-assay Precision
Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-assay Precision
Three samples of known concentration were tested in ten independent assays to assess inter-assay precision.
Preparation and Storage
Store at 4 degree C. Shelf Life: 12 months from manufacture, see label for expiration date
Product Note
Our ELISA Kit assays are dynamic research tools and sometimes they may be updated and improved. If the format of this assay is important to you then please request the current manual or contact our technical support team with a presales inquiry before placing an order. We will confirm the current details of the assay. We cannot guarantee the sample manual posted online is the most current manual.
Other Notes
Small volumes of SERPINE1 elisa kit vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS135492 is a ready-to-use microwell, strip-or-full plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Multiple PAI-1 functional assay (SERPINE1) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing SERPINE1. The ELISA analytical biochemical technique of the MBS135492 kit is based on SERPINE1 antibody-SERPINE1 antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect SERPINE1 antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, SERPINE1. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

Intended Uses: This human PAI-1 activity assay is for the quantitative determination of active plasminogen activator inhibitor type 1 in human plasma. For research use only.

Principle of the Assay: Functionally active PAI-1 present in plasma reacts with urokinase coated and dried on a microtiter plate. Latent or complexed PAI-1 will not bind to the plate or be detected. Unbound PAI-1 samples are aspirated and an anti-PAI-1 primary antibody is added. Excess primary antibody is then aspirated. The bound antibody, which is proportional to the original active PAI-1 present in the samples, is then reacted with the horseradish peroxidase conjugated secondary antibody. Following an additional washing step, TMB substrate solution is then used for color development at 450nm. The amount of color development is directly proportional to the concentration of active PAI-1 in the sample.

Background: PAI-1 is involved in the regulation of the blood fibrinolytic system. Increased plasma levels of PAI-1 are implicated in the impairment of fibrinolytic function and may be associated with thrombotic diseases [1,2]. Levels of PAI-1 increase with age [5] and are elevated in conditions such as normal pregnancy [3] and sepsis [4].

NCBI Summary for SERPINE1
This gene encodes a member of the serine proteinase inhibitor (serpin) superfamily. This member is the principal inhibitor of tissue plasminogen activator (tPA) and urokinase (uPA), and hence is an inhibitor of fibrinolysis. Defects in this gene are the cause of plasminogen activator inhibitor-1 deficiency (PAI-1 deficiency), and high concentrations of the gene product are associated with thrombophilia. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]
UniProt Comments for SERPINE1
SERPINE1: a secreted protein that acts as 'bait' for tissue plasminogen activator, urokinase, and protein C. Its rapid interaction with TPA may function as a major control point in the regulation of fibrinolysis. Belongs to the serpin family. Interacts with VTN. Binds LRP1B; binding is followed by internalization and degradation. Plasma levels of PAI-1 and VCAM-1 together may be useful in predicting post-operative recurrence in patients with colorectal cancer.
