Overview

  • Product name

    FITC Rat IgG1, kappa [RTK2071] - isotype control
    See all Rat isotype controls

  • Conjugation

    FITC. Ex: 493nm, Em: 528nm

  • Conjugation notes

    The antibody was conjugated with FITC under optimal conditions. The solution is free of unconjugated FITC.

    The RTK2071 immunoglobulin reacts with KLH. The RTK2071 immunoglobulin was chosen as an isotype control after screening on a variety of resting, activated, live, and fixed mouse and human tissues.

  • Tested applications

    Suitable for: Flow Cytmore details

  • Immunogen

    Trinitrophenol and KLH.

  • General notes

    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.

Question

Thank you for your help.
I have two additional questions:
- what do you mean as " - no primary - only secondary control" ?
- can you provide a protocol to use the isotype control you suggest?
Thank you for your collaboration

Answer

Thank you for your response.

"No primary control" means that you perform the staining protocol as normal (fixation, blocking, secondary antibody, detection) - except you need to omit the incubation step with the primary antibody. Instead of applying the primary antibody, you only incubate the samples with the dilution buffer you would normally use for diluting the primary antibody.

Isotype control meansyou perform the staining protocol as normal butt the samples will be treated with the isotype control instead of the primary antibody. The isotype of this primary antibody is IgG1, so the isotype control is rat IgG1 .

I would advise you to visit this site to get some further information about positive control and isotype control:

Question

Inquiry: Dear custumer service, we recently used your HCN4 antibody (ab32675) to perform an immunofluorescence assay on human atrial and ventricular myocytes. Staining was succesful and this data were submitted for publication. One of the reviewer asked to have a negative control, e.g. a cell stained with the HCN4 antibody pre-absorbed with the specific peptide. How can we meet this request? do you have a specific peptide and a suitable protocol to perform this assay? thank you for your assistance. Best

Answer

Thank you for your enquiry and your interest in our products.

The immunogen used to raise this antibody was a synthetic peptide: SHGSLLLPPA SSPPPPQVPQ RRGTPPLTPG RLTQDLKL, corresponding to amino acids 1048-1085 of Human HCN4:SHGSLLLPPASSPPPPQVPQRRGTPPLTPGRLTQDLKL. Unfortunately, the peptide is not commercially available.

Even though the immunogen peptide is not available, you could apply several controls to check the specificity of this antibody:

- isotype control,

- negative control,

- no primary - only secondary control

The isotype of this antibody is IgG1 so you can apply an isotype control using rat IgG1 (ab46745, ab128477, ab18403, ab18404, ab18407).

HCN4 is highly expressed in thalamus, testis and in heart, both in ventricle and atrium. It is detected at much lower levels in amygdala, substantia nigra, cerebellum and hippocampus. Generally, negative controls are cells/tissue which do not express the target protein or at very low level. You may find some useful information about expression level of HCN4 at this site: http://www.proteinatlas.org/ENSG00000138622
