Growth Promoter Array
State of the Art Biochip Array Technology
The abcd Biochip Array Technology is used to perform
simultaneous quantitative detection of multiple analytes from a single sample. The core
technology is the Randox Biochip, a solid-state device containing an array of discrete test
regions containing immobilised antibodies specific to different growth promoters. A
competitive chemiluminescent immunoassay is employed for the Growth Promoter Array.
Increased levels of analyte in a specimen will lead to decreased binding of analytes
labelled with horseradish peroxidase (HRP) and thus a decrease in the
chemiluminescence signal being emitted. The light signal generated from each of the test
regions on the biochip is detected using digital imaging technology and compared to that
from a stored calibration curve. The concentration of analyte present in the sample is
calculated from the calibration curve. Ease of Use
Each abcd biochip contains an array of immobilised
antibodies and is ready to use. All liquid reagents are either ready to use, or require
simple dilution. Urine samples can be assayed after simple dilution, although a
column clean-up is required for nandrolone and stilbenes. The use of a
chemiluminescent signal means that no radioactive materials are involved. Results
are processed automatically using dedicated software. Only 100µl of sample is
required, and simultaneous analysis of 45 samples for the 7 drug residues means that
315 test results can be obtained in less than 2.5 hours.

Assay Performance in Urine Following Simple Dilution
The growth promoter array can be used to assess urine samples following simple
• The use of discrete test regions, containing highly specific antibodies, means that
data can be obtained for 7 groups of growth promoters from just 100µl of urine.
• Typical measuring range of 0-5 ng/ml.
• Typical sample recovery at around 2 ng/ml of 88-121%.
• Typical intra-assay precision at around 2 ng/ml of ≤10% and inter-assay precision of ≤11%. 8. Capture images using dedicated software.
