Full Name: EMILIN-1 ELISA Kit (Elastin Microfibril Interface Located Protein 1)
Reactivity: Human
Sample Type: Plasma, Tissue Homogenates, Serum, Biological Fluids
Sensitivity: 0.469 ng/ml


EMILIN-1, also known as Elastin Microfibril Interface Located Protein 1 is a glycoprotein, in the matrix (ECM) of dynamic tissues. Its primary function is to connect fibers to microfibrils within the ECM.

In humans the EMILIN-1 gene is located on chromosome 2p23.3 and encodes a preproprotein consisting of 993 amino acids. Once processed the mature protein becomes part of the ECM. It contains domains for cell adhesion enabling its attachment to components within the ECM. EMILIN-1 binds to microfibrils through integrin binding domains and interacts with tropoelastin through its C terminal portion.

EMILIN-1 exhibits expression levels in elastic tissues such as blood vessels, skin, lungs, etc. It promotes elastogenesis by facilitating the organized deposition of tropoelastin onto microfibrils leading to the formation of fibers. Moreover, it aids in transforming growth factor (TGF beta) signaling which regulates cell growth and synthesis of ECM components. Mutations in EMILIN-1 have been linked to disorders while dysregulation of this protein has associations, with lymphedema, hypertension, stroke, and arthritis.


Human EMILIN-1 ELISA kit can measure concentrations of elastin microfibril interface located protein 1 (EMILIN-1) present is plasma, serum, biological fluids or tissue homogenate samples.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
