  • Relevance

    Function: In cooperation with other chaperones, the Hsp70 family stabilize preexistent proteins against aggregation and mediate the folding of newly translated polypeptides in the cytosol as well as within organelles. These chaperones participate in all these processes through their ability to recognize nonnative conformations of other proteins. They bind extended peptide segments with a net hydrophobic character exposed by polypeptides during translation and membrane translocation, or following stress-induced damage. In case of rotavirus A infection, serves as a post-attachment receptor for the virus to facilitate entry into the cell. Tissue specificity: HSPA1B is testis-specific.
  • Cellular localization

    Cytoplasm. Localized in cytoplasmic mRNP granules containing untranslated mRNAs.

  • ab53496 staining Hsp70 in LLC-PK1 cells expressing Hsp70 under cold block conditions, by Immunocytochemistry/ Immunofluorescence.

    Cells were fixed with 4% paraformaldehyde, permeabilized with 0.01% Triton X-100 in PBS for 4 minutes and blocked with 1% BSA/PBS for 20 minutes. Samples were incubated with primary antibody overnight at 4°C.
  • Overlay histogram showing Jurkat cells stained with ab53496 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab53496, 0.5µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG2a [ICIGG2A] (ab91361, 1µg/1x106 cells) used under the same conditions. Unlabelled sample (blue line). Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter. This antibody gave a positive signal in Jurkat cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

Vielen Dank für Ihre Antwort.

Die Frau Hoffmann ist außer Haus und ich hoffe es ist Ihnen Recht, dass ich mich um Ihren Fall kümmere.

Unser AbTrial ist nur ein Angebot, welches Sie nicht in Anspruch nehmen müssen. Natürlich können Sie jedes unserer Produkte bestellen dass Sie möchten ohne jegliche weitere Verpflichtung.

Ich hoffe dies hilft Ihnen weiter und ich wünsche Ihnen viel Glück mit Ihren Versuchen.

Vielen Dank für Ihren Anruf und für Ihr Interesse an unseren Produkten.

Leider muss ich Ihnen bestätigen, dass ab53496 und ab79275 nicht in ELISA getestet sind und deshalb auch nicht unserer Garantie unterliegen. Wir wissen auch nicht ob beide Klone das gleiche Epitope binden, da die Epitope nicht gemapped wurden.

Vielleicht finden Sie in unserer Auswahl an anti HSP70 Antikörpern, die schon für ELISA getestet sind ein gutes Pärchen.

Für humane Proben würde ich folgendes vorschlagen:

ab47455 als capture Antikörper und ab48515 als Detektionsantikörper. Prinzipiell ist es von Vorteil einen polyklonalen Detektionsantikörper zu verwenden, da die Signalstärke besser ist und auch eine Epitop-Überlappung weniger wahrscheinlich ist.

Diese zwei Antikörper sind noch nicht in einen sandwichELISA getestet worden. Deshalb würde ich Ihnen folgendes Testprogramm vorschlagen: Abtrial

Bitte lassen Sie mich wissen, ob Sie gerne daran teilnehmen möchten und mit welchen Antikörpern. Ich habe Ihre Bestellung noch nicht weitergegeben.

Thank you for contacting us.

The doublets using ab53496are not always well resolved because there is only ˜1kDa between them. The lab was able to provide the attached image showing the doublet on bovine MDBK cells at a 1:1000 dilution. I hope this helps, please let me know if you need any additional information or assistance.
