The DAPP1 Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect DAPP1 protein expression profile in cells. The kit can be used for measuring the relative amounts of DAPP1 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie siRNA or chemicals), or activators have on DAPP1.

Qualitative determination of DAPP1 concentration is achieved by an indirect ELISA format. In essence, DAPP1 is captured by DAPP1-specific primary antibodies while the HRP-conjugated secondary antibodies bind the Fc region of the primary antibody. Through this binding, the HRP enzyme conjugated to the secondary antibody can catalyze a colorimetric reaction upon substrate addition. Due to the qualitative nature of the Cell-Based ELISA, multiple normalization methods are needed:

1. A monoclonal antibody specific for human GAPDH is included to serve as an internal positive control in normalizing the target absorbance values.
2. Following the colorimetric measurement of HRP activity via substrate addition, the Crystal Violet whole-cell staining method may be used to determine cell density. After staining, the results can be analysed by normalizing the absorbance values to cell amounts, by which the plating difference can be adjusted.

*Note: Protocols are specific to each batch/lot. For the correct instructions please follow the protocol included in your kit.

StepProcedure
1.Seed 200 µL of 20,000 adherent cells in culture medium in each well of a 96-well plate. The plates included in the kit are sterile and treated for cell culture. For suspension cells and loosely attached cells, coat the plates with 100 µL of 10 µg/ml Poly-L-Lysine (not included) to each well of a 96-well plate for 30 minutes at 37°C prior to adding cells.
2.Incubate the cells for overnight at 37°C, 5% CO2.
3.Treat the cells as desired.
4.Remove the cell culture medium and rinse with 200 µL of 1x TBS, twice.
5.Fix the cells by incubating with 100 µL of Fixing Solution for 20 minutes at room temperature. The 4% formaldehyde is used for adherent cells and 8% formaldehyde is used for suspension cells and loosely attached cells.
6.Remove the Fixing Solution and wash the plate 3 times with 200 µL 1x Wash Buffer for five minutes each time with gentle shaking on the orbital shaker. The plate can be stored at 4°C for a week.
7.Add 100 µL of Quenching Buffer and incubate for 20 minutes at room temperature.
8.Wash the plate 3 times with 1x Wash Buffer for 5 minutes each time.
9.Add 200 µL of Blocking Buffer and incubate for 1 hour at room temperature.
10. Wash 3 times with 200 µL of 1x Wash Buffer for 5 minutes each time.
11.Add 50 µL of 1x primary antibodies (Anti-DAPP1 Antibody and/or Anti-GAPDH Antibody) to the corresponding wells, cover with Parafilm and incubate for 16 hours (overnight) at 4°C. If the target expression is known to be high, incubate for 2 hours at room temperature.
12.Wash 3 times with 200 µL of 1x Wash Buffer for 5 minutes each time.
13.Add 50 µL of 1x secondary antibodies (HRP-Conjugated AntiRabbit IgG Antibody or HRP-Conjugated Anti-Mouse IgG Antibody) to corresponding wells and incubate for 1.5 hours at room temperature.
14.Wash 3 times with 200 µL of 1x Wash Buffer for 5 minutes each time.
15.Add 50 µL of Ready-to-Use Substrate to each well and incubate for 30 minutes at room temperature in the dark.
16.Add 50 µL of Stop Solution to each well and read OD at 450 nm immediately using the microplate reader.

(Additional Crystal Violet staining may be performed if desired – details of this may be found in the kit technical manual.)
