ターゲット情報

  • 機能

    Molecular calcium-binding chaperone promoting folding, oligomeric assembly and quality control in the ER via the calreticulin/calnexin cycle. This lectin interacts transiently with almost all of the monoglucosylated glycoproteins that are synthesized in the ER. Interacts with the DNA-binding domain of NR3C1 and mediates its nuclear export.

  • 配列類似性

    Belongs to the calreticulin family.

  • ドメイン

    Can be divided into a N-terminal globular domain, a proline-rich P-domain forming an elongated arm-like structure and a C-terminal acidic domain. The P-domain binds one molecule of calcium with high affinity, whereas the acidic C-domain binds multiple calcium ions with low affinity.
    The interaction with glycans occurs through a binding site in the globular lectin domain.
    The zinc binding sites are localized to the N-domain.
    Associates with PDIA3 through the tip of the extended arm formed by the P-domain.

  • 細胞内局在

    Endoplasmic reticulum lumen. Cytoplasm > cytosol. Secreted > extracellular space > extracellular matrix. Cell surface. Also found in cell surface (T cells), cytosol and extracellular matrix. Associated with the lytic granules in the cytolytic T-lymphocytes.

Answer

Thank you for contacting us.

The size of antibody as IgG is 150 kDa (25 kDa of each light chain and ˜53 kDa of each heavy chain).

The size of protein as mentioned before is 417 amino acid 48kDa.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

"may i know the molecular weight and size of the calreticulin antibody-ER Marker, ab4109. ty"

Read More
Answer

Thank you for contacting us.

The predicted size of unprocessed protein is 48kDa (http://www.uniprot.org/uniprot/P27797). The observed size will be higher than predicted because of post translational modifications at amino acid 48,159, 209 and 344.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Question

I am looking for an Arabidopsis calreticulin antibody that
is suitable for Western blot
and/ or immunoprecipitation.
Internet search engines show an old entry for your
antibody ab2907,
but when I open your homepage, this reference is no longer
available.
Is there any Arabidopsis calreticulin antibody available?

Read More
Answer

Thank you for contacting us.

The antibody ab2907 was tried in Arabidopsis by a customer, and the results were submitted as an Abreview (2 out of 5 stars): https://www.abcam.com/Calreticulin-antibody-ER-Marker-ab2907.html&tab=abreviews&intabreviewid=24966

Thus, the Arabidopsis data is on the datasheet, but due to the rating of the results we do not list Arabidopsis as tested species or guarantee the antibody for it.

I have checked the homology of Arabidopsis with the human sequence and the homology is only 54% (isoform 1), 55% (isoform 2), and 49% (isoform 3) - thus very low. It is similar for the rabbit sequence: the homology between rabbit and Arabidopsis is also only 54%.
We usually suggest a sequence homology of 85% or higher forpotentialcross-reactivity. Thus, in generell it would be difficult to find an antibody raised against human or rabbit to be able to crossreact with Arabidopsis.

I might suggest to check http://www.biocompare.com for an antibody that was raised against an Arabidopsis sequence.

I hope this information is of some help to you. Please do not hesitate to contact us if you need any more advice or information.

Question

Hi, I need to know if this calreticulin 4109 will be good for elisa assays. I am doing an inhibition assay where I incubate human sera with the antiserum (polyclonal) against calreticulin and then search for binding of the antiserum to the calreticulin conatined in the serum. Please let me know if I can use your polyclonal antibody for that and also at what conc, would I have to use it for this type of assay?

Read More
Answer

This antibody has not been tested for use in ELISA assays. As it is supplied as a serum, it would not be suitable for use as a coating antibody. There is no immunological reason why it could not be used as a detection antibody, but we cannot guarantee its use in this application.
