Kit Principle Aviva Systems Biology ID4 ELISA Kit (Human) (OKCA00660) is based on standard sandwich enzyme-linked immuno-sorbent assay technology. An antibody specific for ID4 has been pre-coated onto a 96-well plate (12 x 8 Well Strips). Standards or test samples are added to the wells, incubated and removed. A biotinylated detector antibody specific for ID4 is added, incubated and followed by washing. Avidin-Peroxidase Conjugate is then added, incubated and unbound conjugate is washed away. An enzymatic reaction is produced through the addition of TMB substrate which is catalyzed by HRP generating a blue color product that changes to yellow after adding acidic stop solution. The density of yellow coloration read by absorbance at 450 nm and is quantitatively proportional to the amount of sample ID4 captured in the well.

Kit Reproducibility Intra-assay Precision: 3 samples with known low, middle and high level ID4 were tested with 20 replicates across one plate.
Inter-assay Precision: 3 samples with known low, middle and high level ID4 were tested on three different plates with 8 replicates, respectively.

Gene Symbol ID4
Official Gene Full Name Inhibitor of DNA binding 4, HLH protein
Alias Symbols bHLHb27, BHLHB27, Class B basic helix-loop-helix protein 27, DNA-binding protein inhibitor ID-4, IDB4, Inhibitor of DNA binding 4
NCBI Gene Id 3400
Protein Name DNA-binding protein inhibitor ID-4
Description of Target Transcriptional regulator (lacking a basic DNA binding domain) which negatively regulates the basic helix-loop-helix (bHLH) transcription factors by forming heterodimers and inhibiting their DNA binding and transcriptional activity. Implicated in regulating a variety of cellular processes, including cellular growth, senescence, differentiation, apoptosis, angiogenesis, and neoplastic transformation.
