Plate: Pre-coated

Protocol: human THBS1 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for THBS1 has been precoated onto 96-well plates. Standards(NSO, N19-P1170) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for THBS1 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 human THBS1 amount of sample captured in plate.

Assay Procedure:

Aliquot 0.1 mL per well of the 100 ng/mL, 50 ng/mL, 25 ng/mL, 1.25 ng/mL, 6.25 ng/mL, 3.12 ng/mL, 1.56 ng/mL human THBS1 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 human cell culture supernates, serum or plasma(heparin, EDTA) to each empty well. See "Sample Dilution Guideline" above for details. We recommend that each human THBS1 standard solution and each sample is measured in duplicate.

Assay Precision:

• Sample 1: n=16, Mean(ng/ml): 15.5, Standard deviation: 0.93, CV(%): 6
• Sample 2: n=16, Mean(ng/ml): 32, Standard deviation: 1.76, CV(%): 5.5
• Sample 3: n=16, Mean(ng/ml): 52, Standard deviation: 2.08, CV(%): 4,
• Sample 1: n=24, Mean(ng/ml): 16.3, Standard deviation: 1.27, CV(%): 7.8
• Sample 2: n=24, Mean(ng/ml): 38, Standard deviation: 2.47, CV(%): 6.5

Background:

Protein Function: Adhesive glycoprotein that mediates cell-to-cell and cell-to-matrix interactions. Binds heparin. May play a role in dentinogenesis and/or maintenance of dentin and dental pulp (By similarity). Ligand for CD36 mediating antiangiogenic properties. Plays a role in ER stress response, via its interaction with the activating transcription factor 6 alpha (ATF6) which produces adaptive ER stress response factors (By similarity). .

Background: Thrombospondin 1, also known as THBS1, is a protein that in humans in encoded by the THBS1 gene. Thrombospondin 1 is a subunit of a disulfide-linked homotrimeric protein. This protein is an adhesive glycoprotein that mediates cell-to-cell and cell-to-matrix interactions. By in situ hybridization, the THBS1 gene was mapped to human 15q15 and the cognate gene to mouse chromosome 2(region F) and was localized to 15q11-qter by Southern analysis of human-rodent somatic cell hybrids. Thrombospondin I is a multimodular secreted protein that associates with the extracellular matrix and possesses a variety of biologic functions, including a potent antiangiogenic activity. Other thrombospondin genes include thrombospondins II, III, and IV.
