Add substrate solution and continue

Incorrect storage condition

Check if the kit is stored at recommended condition and used before expiration date

     

Poor Standard Curve

Standard was incompletely reconstituted or was inappropriately stored

Aliquot reconstituted standard and store at  -70 ℃

Imprecise / inaccurate pipetting

Check / calibrate pipettes

Incubations done at inappropriate temperature, timing or agitation

Follow the general ELISA protocol

Background wells were contaminated

Avoid cross contamination by using the sealer appropriately

     

Poor detection value

The concentration of antigen in samples was too low

Enriching samples to increase the concentration of antigen

Samples were ineffective

Check if the samples are stored at cold environment. Detect samples in timely manner

     

High Background

Insufficient washes

Use multichannel pipettes without touching the reagents on the plate

Increase cycles of washes and soaking time between washes

TMB Substrate Solution was contaminated

TMB Substrate Solution should be clear and colorless prior to addition to wells

Materials were contaminated

Use clean plates, tubes and pipettes tips

     

Non-specificity

Samples were contaminated

Avoid cross contamination of samples

The concentration of samples was too high

Try higher dilution rate of samples

Background

Coagulation factor VII, also known as Serum prothrombin conversion accelerator, Factor VII, F7 and FVII, is a member of the peptidase S1 family. Factor VII is one of the central proteins in the coagulation cascade. It is an enzyme of the serine protease class. Factor VII contains two EGF-like domains, one Gla (gamma-carboxy-glutamate) domain and one peptidase S1 domain. The main role of factor VII is to initiate the process of coagulation in conjunction with tissue factor (TF). Tissue factor is found on the outside of blood vessels, normally not exposed to the blood stream. The action of the Factor VII is impeded by tissue factor pathway inhibitor (TFPI), which is released almost immediately after initiation of coagulation. Factor VII is vitamin K dependent and is produced in the liver. The use of warfarin or similar anticoagulants impairs its function. Upon vessel injury, tissue factor is exposed to the blood and circulating Factor VII. Once bound to TF, FVII is activated to FVIIa by different proteases, among which are thrombin (factor IIa), factor Xa, IXa, XIIa, and the FVIIa-TF complex itself. The most important substrates for FVIIa-TF are Factor X and Factor IX.
