Catalog

The NGF Emax® ImmunoAssay Systems provide optimized reagents and a protocol for the sensitive and specific detection of biologically active nerve growth factor (NGF). After an overnight coating of a 96 well plate, the specific protein is detected using an antibody sandwich format. The systems use horseradish peroxidase-conjugated secondary antibody for the final chromogenic detection of bound neurotrophic factor. The system can be used to quantitate NGF in tissue culture supernatants and tissue extracts in the range of 7.8–500pg/ml. Avoid using samples containing high levels of IgG such as serum, plasma and spleen.

  • Specificity: Specific detection of respective factor; less than 3% cross-reactivity with other related neurotrophic and growth factors.
  • Sensitivity: Detects a minimum of 15.6pg/ml of NGF.
  • Standard Range: 7.8–500pg/ml
  • Recommended Plate: Nunc Maxisorp™, Dynex Immulon®-4 and Costar plates

Technical Literature

The complete protocol is found in Technical Bulletin #TB226

Product Improvements

The Emax® ImmunoAssay Systems have been improved to provide longer shelf-life and ease of use. The key improvements include newly formulated horseradish peroxidase (HRP) conjugates that provide increased stability and easier dilutions, and a new ready-to-use, single-component TMB substrate. The entire system is now stored at –20°C for up to 6 months from the date of receipt, before thawing and using. Once thawed the product should be stored at 4°C for up to three months.
