Purpose The human SPARCL1 ELISAkit is for the quantitative determination of human SPARCL1.
This ELISA Pair Set contains the basic components required for the development of sandwich ELISAs.
Detection Method Colorimetric
Sensitivity 93.75 pg/mL
Characteristics Capture Antibody: 1.0 mg/mL of mouse anti-SPARCL1 monoclonal antibody. Dilute to a working concentration of 2.0 μg/mL in CBS before coating.

Detection Antibody: 0.5 mg/mL mouse anti-SPARCL1 monoclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to working concentration of 1.0 μg/mL in detection antibody dilution buffer before use.

Standard: Each vial contains 160 ng of recombinant SPARCL1. 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 usi ng 2-fold serial dilutions in sample dilution buffer, and a high standard of 6000 pg/mL is recommended.

Sensitivity: The minimum detectable dose of human SPARCL1 was determined to be approximately 93.75 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 SPARCL1
Background SPARC-like protein 1 ( SPARCL1, also known as SC1, high endothelial venule protein, or hevin) is an extracellularmatrix-associated, secreted glycoprotein belonging to the SPARC (secreted protein acidic and rich in cysteine) family ofmatricellular proteins. It contains three conserved structural domains that are implicated in the regulation of celladhesion, migration, and proliferation. SPARCL1 is expressed in a wide range of tissues, such as tissues of the lymphnode, brain, heart, lung, skeletal muscle, ovary, small intestine, and colon. SPARCL1 has antiadhesive properties, andloss of SPARCL1 expression is associated with increased proliferative activity and cell cycle progression. It issuggested that it may influence multiple cellular processes during distinct stages of brain development and function. SC1 may also be involved in the pathogenesis of multiple neural traumas and function as a tumor suppressor andregulator of angiogenesis, and is aberrantly expressed in brain tumors.
Research Area Cancer
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 antibodyspecific for SPARCL1 coated on a 96-well plate. Standards and samples are added tothe wells, and any SPARCL1 present binds to the immobilized antibody. The wells are washedand a horseradish peroxidase conjugated mouse anti-SPARCL1monoclonal antibody is then added, producing anantibody-antigen-antibody "sandwich". The wells are again washed and TMBsubstrate solution is loaded, which produces color in proportion to the amountof SPARCL1 present in the sample. To end the enzyme reaction, the stopsolution 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.
