Application Details

Application Notes: Before using Kit, spin tubes and bring down all components to bottom of tube. Duplicate well assay was recommended for both standard and sample testing.

Plate: Pre-coated

Protocol: mouse ESM1 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from rat specific for ESM1 has been precoated onto 96-well plates. Standards(NSO, W20-R184) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for ESM1 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the mouse ESM1 amount of sample captured in plate.

Assay Procedure:

Aliquot 0.1 mL per well of the 1500pg/mL, 750pg/mL, 375pg/mL, 187.5pg/mL, 93.7pg/mL, 46.8pg/mL, 23.4pg/mL mouse ESM1 standard solutions into the precoated 96-well plate. Add 0.1 mL of the sample diluent buffer into the control well (Zero well). Add 0.1 mL of each properly diluted sample of mouse cell culture supernates, serum or plasma(heparin, EDTA) to each empty well. See "Sample Dilution Guideline" above for details. It is recommended that each mouse ESM1 standard solution and each sample be measured in duplicate.

Assay Precision:

• Sample 1: n=16, Mean(pg/ml): 56, Standard deviation: 1.85, CV(%): 3.3
• Sample 2: n=16, Mean(pg/ml): 673, Standard deviation: 31.6, CV(%): 4.7
• Sample 3: n=16, Mean(pg/ml): 1033, Standard deviation: 57, CV(%): 5.5,

Background:

Protein Function: Involved in angiogenesis, promotes angiogenic sprouting. May have potent implications in lung endothelial cell-leukocyte interactions (By similarity). .

Background: Endothelial cell-specific molecule 1, also known as Endocan, is a protein that in humans is encoded by the ESM1 gene. This gene encodes a secreted protein which is mainly expressed in the endothelial cells in human lung and kidney tissues. The expression of this gene is regulated by cytokines, suggesting that it may play a role in endothelium-dependent pathological disorders. The transcript contains multiple polyadenylation and mRNA instability signals. ESM-1 has been described as a specific biomarker of tip cells during neoangiogenesis by independent teams. Its expression has been shown to be increase in presence of pro-angiogenic growth factors such as VEGF(vascular endothelial growth factor) or FGF-2(fibroblast growth factor 2).
