Anti-FLAG® Coated Plates

In the era of high-content screening, scientists are trying to identify rapid, automated formats for immunosorbent assays (ELISA). The ANTI-FLAG High Sensitivity 96-well plates provide a convenient, high-throughput platform for the capture and detection of recombinant FLAG fusion proteins (Figures 1 and 2). The ANTI-FLAG® High Sensitivity plates are coated with the mouse monoclonal M2 antibody and pre-blocked to provide timesavings for high-throughput users. The M2 monoclonal antibody is covalently bound to the plate in a favorable orientation such that the Fab region of the antibody is available for the epitope tag to provide greater specificity. The ANTI-FLAG coating can detect as little as 1 ng/well with a capacity of up to 300 ng/well of FLAG fusion protein.

An automated method for high-throughput ELISA applications has been developed and validated for the ANTI-FLAG High Sensitivity plates. The following resources are available for download: Automated Method and Automated Protocol for use with the Sciclone ALH 3000 Workstation from Caliper Life Sciences.

Applications

  • Screening for expression
  • Protein: protein interaction assays
Features

Rapid Procedure

96 samples can be processed from cell lysis through recombinant protein purification in 4-5 hours.

Enhanced Productivity

Walk-away automation of recombinant FLAG fusion protein capture and detection by ELISA allows you to concentrate on other aspects of your work.

Simplified Handling

The optimized, pre-blocked M2 monoclonal antibody coating eliminates several time-consuming steps associated with traditional ELISA experiments.

High Sensitivity

The ANTI-FLAG coating can detect as little as 1 ng/well of FLAG fusion protein.

Sample Data

Automated Capture and ELISA Analysis of a FLAG-fusion Protein

Figure 1. Standard curve generated from diluted FLAG-Bacterial Alkaline Phosphatase (BAP) standards. The automated Sciclone method was used to perform an ELISA. FLAG- BAP protein was serially diluted and then incubated at room temperature for 2 hours in the ANTI-FLAG M2 coated plate. For ELISA analysis, the BAP protein was first incubated with rabbit anti-alkaline phosphatase antibody for 1 hour at room temperature. Following four wash steps, the BAP protein was then incubated with the secondary antibody, a goat anti-rabbit IgG peroxidase conjugate, for 1 hour at room temperature. The peroxidase was detected by using a soluble TMB substrate for ELISA applications. The reaction was stopped using TMB stop solution. Absorbance was read on a Molecular Devices SpectraMax® Plus384 at 450 nm.

Cross Contamination Analysis
Figure 2. Cross contamination analysis using FLAG-BAP protein standard and blank wells. Cross contamination was evaluated in the automated ELISA method by inserting blanks between rows of FLAG-BAP protein standards. For ELISA analysis, the BAP protein was first incubated with rabbit anti-alkaline phosphatase antibody for 1 hour at room temperature. Following four wash steps, the BAP protein was then incubated with the secondary antibody, a goat anti-rabbit IgG peroxidase conjugate, for 1 hour at room temperature. The peroxidase was detected by using a soluble TMB substrate for ELISA applications. The reaction was stopped using TMB stop solution. Absorbance was read on a Molecular Devices SpectraMax® Plus384 at 450 nm. No cross contamination was detected in the blanks.
