Protein S Antigen by ELISA
Protein S is a vitamin K-dependent plasma protein synthesized
in the liver, vascular endothelium and megakaryocytes.
It is a necessary cofactor for Protein C and deficiency
may lead to serious thrombotic events. In normal plasma,
about 60% of Protein S is complexed to C4b-binding protein,
while 40% circulates in its functionally active free form.
Protein S ELISA Assay
Kit
- Rapid, easy-to-use antibody capture ELISA format
- Simultaneous measurement of Free and Total Protein
S by pretreating with PEG; results expressed as relative
percent (%) of normal
- Accurate detection of Protein S antigen levels as
low as 5% of normal
- 6-point reference curve
- Linearity, expressed as the coefficient of determination
(r2) is 0.985 for Total, and 0.992 for Free Protein
S. Mean accuracy is 101% for Total, and 98% for Free
Protein S.
Monoclonal Free Protein
S Antigen by ELISA uses a monoclonal antibody specific
for Free Protein S in an ELISA format to measure Free
Protein S directly without PEG precipitation.

Von Willebrand Factor
Von Willebrand Factor (vWF)
is a procoagulant protein, that mediates platelet adhesion
to sites of vascular injury and protects F.VIII from proteolytic
cleavage in circulation. The most common inherited bleeding
disorder is von Willebrand Disease (vWD), caused by either
quantitative (Type I) or qualitative (Type II) deficiencies
in vWF. While about 80% of vWD is Type I, both qualitative
(functional) and quantitative (antigenic) assays may be
required for laboratory diagnosis of vWD.
vWF:Ag ELISA Assay Kit
- Easy-to-perform ELISA method with rapid turnaround
time
- Results expressed in relative percent (%) of normal
and standardized against established reference preparations
- Accurate detection of vWF:Ag levels as low as 5%
of normal
- Less subjective interpretation of results than Laurell
rocket EID methods
- 6-point reference curve
- Linearity, expressed as the coefficient of determination
(r2) is 0.995. Mean accuracy is 103.6%.
