Key features and details
- Rabbit polyclonal to R2D2
- Suitable for: WB
- Reacts with: Drosophila melanogaster
- Isotype: IgG
Product nameAnti-R2D2 antibody
DescriptionRabbit polyclonal to R2D2
SpecificityThe antibody specifically recognises the immunising peptide in a blocking western blot. All four observed bands are blocked, showing that they are specific. There is also low background and high titre in ELISA. Please let us know if you can explain these bands.
Tested applicationsSuitable for: WBmore details
Species reactivityReacts with: Drosophila melanogaster
Synthetic peptide corresponding to Drosophila melanogaster R2D2 aa 100-200 (intracellular) conjugated to keyhole limpet haemocyanin.

Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.
Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.
We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.
In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.
We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.
Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.
Please check that this product meets your needs before purchasing. If you have any questions, special requirements or concerns, please send us an inquiry and/or contact our Support team ahead of purchase.

Our Abpromise guarantee covers the use of ab27650 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 37 kDa (predicted molecular weight: 35 kDa).|
RelevanceThe RNA interference (RNAi) pathway is initiated by processing long double-stranded RNA into small interfering RNA (siRNA). The siRNA-generating enzyme consists of DCR-2 and R2D2. R2D2 is homologous to the Caenorhabditis elegans RNAi protein RDE-4.

Predicted band size: 35 kDa
Observed band size: 37 kDa why is the actual band size different from the predicted?
Additional bands at: 39 kDa (possible cross reactivity), 55 kDa (possible cross reactivity), 85 kDa (possible cross reactivity)
ab27650 specifically recognises a band at 37kDa corresponding to R2D2, which is blocked using the immunising peptide (ab17670).
ab27650 has not yet been referenced specifically in any publications.
