Assay Principle
Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.
To assess the linearity of the assay, samples were spiked with high concentrations of human MGP in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

On which data are these pre-measurement storage recommendations based?
Can you confirm these storage recommendations also after review?
Other companies describe different storage recommendations. Do you have an idea how these different information concerning the Matrix Gla Protein can occur?

Thanks for your inquiry.
The sample preparation method is based on the consideration of routine biological experiment and the sample degradation.
Generally, if you can use the sample within short-term, pls keep them stored in-20 degrees;
if you will use the sample within long-term, pls keep them stored in -80 degrees.Certainly it is the best to collect the new and fresh sample.
Collecting fresh sample is not easy to realize, so here advice you to keep them stored as our manual. Avoid repeated freeze-thaw and pollution.
As for the other companies mentioned storage, we cannot verify it and no clear advice to provide here.
This kit is used for scientific research and can detect serum plasma sample. Pls check the manual to find the corresponding sample preparation method.
The method is a mature indeed. Of course, it is best to use the newly collected samples for testing.

I would like to discuss the difference between a trial kit and a full kit to ensure we will get the same results comparatively. Specifically in the Human Matrix Gla Protein, MGP ELISA Kit and the Human Osteocalcin/Bone gla protein, OT/BGP ELISA kit.


It's difficult for us to guarantee that the test results are completely the same. The results are affected by many factors, such as slight differences between different lots, error factors, etc. There are random errors and negligent errors (there are not many such factors, but they cannot be excluded), and the random errors can only be minimized as much as possible and cannot be completely avoided.

Many customers ordered 96T full size after trying our 24T sample kit and no complaints for the 96T full size, which proves that our ELISA kits work well.

PMID: 29529056
  3. Studied serum levels of bone morphogenic protein-4 (BMP-4) and matrix Gla protein (MGP) in patients who were admitted to emergency department with the diagnosis of acute coronary syndrome (ACS) and underwent primary percutaneous coronary intervention. MGP and BMP-4 levels were significantly elevated when compared to subjects with normal coronary arteries. PMID: 28605143
  4. genetic association studies in population in Greece: Data suggest that an SNP in promoter region of matrix Gla protein (rs1,800,802; T-138C) is associated with diabetic angiopathy (as indicated by carotid intima media thickness) in patients with type 2 diabetes and diabetic nephropathy.

  14. circulating dp-ucMGP and dp-cMGP may have a role in increasing risk of all-cause and cardiovascular mortality PMID: 24835435
