Soluble Platelet Endothelial Cell Adhesion Molecule-1 (sPECAM-1) ELISA Kit


Human sPECAM-1 ELISA kit is a method for measuring in vitro quantitative levels of soluble platelet/endothelial cell adhesion molecule-1 (sPECAM1, CD31, sPECAM-1) in human serum, cell lysates, plasma, biological fluids and cell culture supernatant. This assay has a minimum sensitivity limit of 0.22 ng/ml.


PECAM1 or CD31 is a member of the immunoglobulin gene superfamily and plays important roles in removing aged neutrophils from the body. PECAM-1 is found to be widely distributed on vascular system cells which are responsible for mediating cellular interactions using either heterophilic or homophilic adhesive mechanisms. The following sPECAM-1 ELISA kit is designed for analysing various diagnostic applications. CD31 is predominately found to be located on macrophages, platelets, granulocytes, megakaryocyte, osteoclasts and lymphocytes (including B cells, B cells or NK cells). There have been lots of findings to indicate that it may be involved in angiogenesis, integrin activation and leukocyte transmigration. Soluble PECAM-1 is also known to be expressed in a number of tumors, such as vascular tumors, epithelioid hemangioendothelioma, plasmacytomas, histiocytic malignancies and epithelioid sarcoma-like hemangioendothelioma. This sPECAM-1 ELISA kit can offer minimum sensitivity levels of 0.22 ng/ml and it is ideal for human plasma, cell culture supernatant, serum, biological fluids and cell lysates samples.


The minimum detection sensitivity level of soluble platelet/endothelial cell adhesion molecule-1 (sPECAM-1, CD31, sPECAM1) using current human sPECAM-1 ELISA kit was 0.22 ng/ml. The dynamic range for this assay is 0.051 – 10 ng/ml.

Your secretory IgA ELISA gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

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.

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.

You are my first point of contact when I am looking to purchase ELISA. You have such an easy and simple system, yet it is very effective.
