Purpose The Human ADAM15 ELISA Pair Set is for the quantitative determination of Human ADAM15.
This ELISA Pair Set contains the basic components required for the development of sandwich ELISAs.
Detection Method Colorimetric
Sensitivity 47 pg/mL
Characteristics Capture Antibody: 1.0 mg/mL of rabbit anti-ADAM15 monoclonal antibody(in PBS, pH 7.4). Dilute to a working concentration of 2 μg/mL in CBS before coating.

Detection Antibody: 0.5 mg/mL rabbit anti-ADAM15 monoclonal antibodyconjugated to horseradish-peroxidase (HRP) (in PBS, 50 % glycerol, pH 7.4). Dilute to working concentration of 0.5 μg/mL in detection antibody dilution buffer before use.

Standard: Each vial contains 96 ng of recombinant ADAM15. Reconstitute with 1 mL detection antibody dilution buffer. After reconstitution, store at -20 °C to -80 °C in a manual defrost freezer. A seven-point standard curve using 2-fold serial dilutions in sample dilution buffer, and a high standard of 3 ng/mL is recommended.

Sensitivity: The minimum detectable dose of Human ADAM15 was determined to be approximately 47 pg/mL. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.

Alternative Name ADAM15
Background The adamalysin (ADAM) metalloproteinase disintegrins, also known as metalloprotease/disintegrin/cysteine-richproteins, are a branch of the metzincin metalloproteinase superfamily that are related to snake venommetalloproteinases and integrin ligands. Human ADAM15 was first named metargidin, and uniquely, it carries an RGDbinding motif in a position similar to that in snake venom disintegrins. ADAM15 is widely expressed in various tissuesand cells, including human umbilical vein endothelial cells and smooth muscle cells, and its expression can be drived byVascular endothelial (VE) -cadherin. Overexpression of ADAM15 in NIH3T3 cells appears to enhance cell-cellinteractions, as suggested by decreased cell migration, altered cell morphology at the wound edge, decreasedmonolayer permeability, and increased cell adhesion to monolayers of cells expressing ADAM15 by retroviraltransduction. ADAM15 plays a physiological roleas a natural binding partner of integrin αvβ3 thereby loosening tumorcell adhesion to the underlying matrix and regulating tumor cell migration and invasion, and functional interplay betweenADAM15 and Src family PTKs may contribute to signaling in hematopoietic cells. Aslo, ADAM15 is believed to interactwith integrins αvβ3, α5β1, and α9β1 through its disintegrin domain. ADAM15 has been shown to degrade collagens Iand IV and to cleave the inflammatory cytokine CD23, thus influence ECM remodeling within rheumatoid synovialtissues and in atherosclerosis. The high expression levels of ADAM15 correlated with advanced metastatic diseases, and a clear association with clinical parameters was determined.
Research Area Proteolysis / Ubiquitin, Metalloprotease, Extracellular Matrix
Application Notes Optimal working dilution should be determined by the investigator.
Protocol This ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for ADAM15 coated on a 96-well plate. Standards and samples are added to the wells, and any ADAM15 present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated rabbit anti-ADAM15 monoclonal antibody is then added, producing an antibody-antigen-antibody "sandwich". The wells are again washed and TMB substrate solution is loaded, which produces color in proportion to the amount of ADAM15 present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.
Reagent Preparation
  1. Dilute the capture antibody to the working concentration in CBS. Immediately coat a 96-well microplate with 100 μL per well of the diluted capture antibody. Seal the plate and incubate overnight at 4 °C.
    2. Aspirate each well and wash with at least 300 μL wash buffer, repeating the process two times for a total of three washes. Complete removal of liquid at each step is essential for good performance. After the last wash, remove any remaining wash buffer by inverting the plate and blotting it against clean paper towels.
    3. Block plates by adding 300 μL of blocking buffer to each well. Incubate at room temperature for a minimum of 1 hour.
    4. Repeat the aspiration/wash as in step 2. The plates are now ready for sample addition.
Assay Procedure
  1. Add 100 μL of sample or standards in sample dilution buffer per well. Seal the plate and incubate 2 hours at roomtemperature.
    2. Repeat the aspiration/wash as in step 2 of plate preparation.
    3. Add 100 μL of the detection antibody, diluted in antibody dilution buffer, to each well. Seal the plate and incubate 1hour at room temperature.
    4. Repeat the aspiration/wash as in step 2 of plate preparation.
    5. Add 200 μL of substrate solution to each well. Incubate for 20 minutes at room temperature (if substrate solutionis not as requested, the incubation time should be optimized). Avoid placing the plate in direct light.
    6. Add 50 μL of stop solution to each well. Gently tap the plate to ensure thorough mixing.
    7. Determine the optical density of each well immediately, using a microplate reader set to 450 nm.
Calculation of Results

Calculate the mean absorbance for each set of duplicate standards, controls and samples. Subtract the mean zero standard absorbance from each. Construct a standard curve by plotting the mean absorbance for each standard on the y-axis against the concentration on the x-axis and draw a best fit curve through the points on the graph. To determine the concentration of the unknowns, find the unknowns' mean absorbance value on the y-axis and draw a horizontal line to the standard curve. At the point of intersection, draw a vertical line to the x-axis and read the concentration. If samples have been diluted, the concentration read from the standard curve must be multiplied by the dilution factor. Alternatively, computer-based curve-fitting statistical software may also be employed to calculate the concentration of the sample.
