Properties

Applications

Our Abpromise guarantee covers the use of ab47027 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Notes
IHC-P 1/400. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
IHC-P Use a concentration of 5 µg/ml.
WB Use a concentration of 1 - 5 µg/ml. Detects a band of approximately 15 kDa (predicted molecular weight: 14 kDa).Can be blocked with Rat CGRP peptide (ab47101).

Target

  • RelevanceCGRP is present in C-cells of the thyroid and in central and peripheral nerves. CGRP has several important physiologic roles: it is a potent vasodilator, and can affect the force and rate of heart beat; it can modulate acetylcholine receptor function at the neuromuscular junction; it has been demonstrated to block tolerance to morphine; and it can modulate antigen presentation in Langerhans cells in the skin. Despite these important physiologic functions, therapeutic strategies using CGRP have been impeded due to the lack of a cloned CGRP receptor with which ligands could be developed.

Anti-CGRP antibody images

  • IHC image of CGRP staining in rat dorsal root ganglion formalin fixed paraffin embedded tissue section, performed on a Leica Bond system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab47027, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

  • Anti-CGRP antibody (ab47027) at 1 µg/ml + Dorsal Root Ganglia (Rat) Tissue Lysate at 10 µg

    Secondary
    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

    Performed under reducing conditions.

    Predicted band size : 14 kDa
    Observed band size : 15 kDa (why is the actual band size different from the predicted?)
  • IHC-P image of CGRP staining on Rat spinal cord sections using ab47027 (1:400). The sections were deparafinized and subjected to heat mediated antigen retrieval. The sections were then blocked using 1% BSA at 21°C for 10 min. The primary antibody was used 21°C for 2 hours.

I can confirm that the immunogen for ab47027spans part of the signal peptide and the first propeptide so it should only detect full length unprocessed CGRP.
