Overview

  • Product name

    Anti-CDK1 antibody [A17]
    See all CDK1 primary antibodies

  • Description

    Mouse monoclonal [A17] to CDK1

  • Host species

    Mouse

  • Specificity

    The antibody inhibits the activation of p34cdc2 kinase by cyclins. A study published in the Biotechniques journal suggests that ab18 cross-reacts with Cep152 protein. This should not be a problem for simple western blot experiments because of the difference in molecular weight (MW) between Cdk1 and Cep152. (Cdk1 has a predicted MW of 34-kDa. Isoforms 1-4 of Cep152 have predicted MW of 147, 158, 189 and 196-kDa respectively.) However, this could potentially cause misleading results in Immunofluorescence and pull down experiments. Abcam welcomes customer feedback.

    This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab18 overnight at 4°C. Antibody binding was detected using an anti-mouse antibody conjugated to HRP, and visualised using ECL development solution.

    Sections were stained using an automated system (Dako PT Link), at room temperature. Sections were rehydrated and antigen retrieved with the Dako 3-in-1 antigen retrieval buffer, EDTA pH 9.0. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 minutes. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 minutes and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.

Question

elen Dank für die Zusendung des CdK1(ab18)-Ersatzrörchens
. Der Antikörper kam leider heute erst an und
der Kühlakku war nicht mehr kühl. Ich hoffe, der AK hat dadurch keinen
Schaden genommen, werde ihn aber erstmal testen.

Answer

Der Antikörper sollte dies eigentlich unbeschadet überstanden haben. Wir versenden unsere Antikörper so z.B. auch nach Australien oder Thailand, und da kann es schon einmal zu Transitzeiten von einer Woche kommen, und bisher haben wir noch keine erhöhten Beschwerderaten für die so versandten Produkte.

Die meisten Antikörper sind für längere Zeit bei Raumtemperatur stabil. Versuche bei Abcam mit Antikörpern, die über einen längeren Zeitraum bei Raumtemperatur gelagert wurden, haben gezeigt, dass die Aktivität erst nach zwei Monaten nachlässt. Dennoch verschicken wir Antikörper als Vorsichtsmaßnahme mit Kühlpaketen, die die Umgebungstemperatur für 48 Stunden bei circa 4°C halten. Dieses verbessert auch die Haltbarkeit der Antikörper und verringert das rapide Auf- und Abkühlen der Antikörper.


Falls es denoch zu Problemen kommen sollte, melden Sie sich bitte uns.

Question

Sehr geehrte Damen und Herren,
ich bitte um technische Hilfestellung zu folgendem Antikörper:
Anti-CDK1 antibody [A17] (ab18), Mouse monoclonal
Ich möchte damit CdK1 in Pancreas Cryoschnitten, wahlweise auch
Paraffinschnitten nachweisen, und parallel dazu Insulin (Abcam, Guinea
Pig). Als Sekundär-AK verwende ich Goat Anti-Mouse-Alexa488 oder-568
bzw. Goat Anti-Guinea-Pig-Alexa568 oder -488. Zellkernfärbung mit DAPI.
Bisher habe ich noch kein spezifisches Signal erhalten. Folgende
Versuche habe ich durchgeführt:
1. CdK1 in Wildtyp Pancreas Cryoschnitten
- frisches Pancreas-Gewebe wurde vor Sucrosereihe und dem einbetten in
Tissue-TEK über Nacht bei 4°C in 4% PFA fixiert
- Cryoschnitte 12um, 30min trocknen, storage -20°C 7 Tage
- Schnitte 30min bei RT trocknen
- Fixation: 15min 4% PFA bei RT
- Blocking und Permeab.: 30min 0.3% Triton in 16% Goat Serum NaPO4
Puffer pH 7.4
- Primary AB über Nacht in Blocking Puffer 4°C: Anti CdK1 1:50 bis 1:200
- Secondary AB 1:200 1h RT in Blocking Puffer (CdK1: Alexa488,
Insulin: Alexa568)
- Ergebnis: unspezifische Färbung auch in Negativ-Kontrolle
2. CdK1 in WT Pancreas Paraffinschnitten
- Gewebe-Fixierung in 4% PFA über Nacht 4°C
- 5um-Schnitte
- Deparaffinisierung in Xylen und Ethanolreihe
- AG-Retrieval: 40min Microwave Boiling in Citratpuffer pH 6.0, 30min abkühlen
- Blocking und Permeab.: 45min RT in 0.2% Saponin 16% Goat Serum NaPO4
Puffer pH 7.4
- Primary AB über Nacht in Blocking Puffer 4°C: Anti CdK1 1:25 bis 1:100
- Secondary AB 1:200 1h RT in Blocking Puffer (CdK1: Alexa488,
Insulin: Alexa568)
-Ergebnis: unspezifische Färbung auch in Negativ-Kontrolle
3. CdK1 in WT Pancreas Paraffinschnitten mit Thermo Scientific Nuclear
Staining Kit
- Paraffinschnitte, Vorrbehandlung und Ag-Retrieval wie bei 2.
- CdK1: Alexa488, Insulin: Alexa568
- Positiv-Kontrolle: BRDU: Alexa546
- siehe Anhang (2012-03-21 CdK1 Test TS Nuclear Staining Kit)
4. CdK1 in WT Dünndarm Paraffinschnitten mit Thermo Scientific Nuclear
Staining Kit (als Positivkontrolle wegen hoher Proliferation im
Dünndarmgewebe)
- Procedure wie bei 3.
- siehe Anhang (2012-03-29 CdK1 (Abcam) TS Nuclear Staining Kit on
Small Intestines)
5. CdK1 in MIN6 Cells: Vergleich Normal CdK1 und CdK1 Overexpression
- Protokoll A: 20min 4% PFA 4°C, Saponin Procedure wie bei 2., Washing
mit Low und High Salt Buffer
- Protokoll B: Abreview
https://www.abcam.com/index.html?datasheet=18&tab=abreviews&intabreviewid=20556
- CdK1: Alexa488
- Kontrollen: Anti-HIS als Positiv-Kontrolle, da das CdK1-Konstrukt
für die Transfektion auch einen HIS-Tag besitzt; CyclinB;
Negativ-Kontrolle: kein Primary AB
- Ergebnis: kein Signal bei CdK1, spezifische Färbung bei HIS, Färbung
bei CyclinB; bessere Färbeergebnisse bei den Kontrollen mit Protokoll B
-siehe Anhang (2012-04-02 CdK1 Test MIN6)
Leider habe ich auch bei Versuch Nr. 5 kein Signal für CdK1 erhalten,
so wie es in dem Abreview-Protokoll für HeLa-Zellen abgebildet ist.
Ich bitte Sie um Ratschläge, wie ich doch noch zu einem Färbeergebnis
kommen kann. Da dies nun schon der dritte Anti-CdK1-AK ist, den ich
erfolglos teste, gehen mir die Ideen aus. Aber irgendwie müssen die
Bilder von CdK1-positiven Zellen und Geweben ja zustande kommen.
Ich freue mich, wenn Sie mir den entscheidenden Hinweis geben können.
Vielen Dank.
Mit freundlichen Grüßen

Answer

Vielen Dank für IhreAnfrage und all dieInformationen.

Es tut mir leid zu hören, dass dieses Röhrchen vonab18 keine guten Ergebnisse liefert. Ich stimme Ihnen zu, dass kein spezifisches Signal erkannt werden kann in all den von Ihnen durchgeführten Experimenten. Deshalb denke ich, dass Sie ein schlechtes Röhrchen erhalten haben.

Der hohe Hintergrund ist sicherlich auf den Sekundären Antikörper zurückzuführen, da auch die Negativkontrolle ohne primären Antikörper diesen Hintergrund anzeigt.

Ich möchte Ihnen außerdem vorschlagen in zukünftigen Versuchen EDTA, pH 9 als Antigendemaskierungspuffer zu verwenden. Dieser Puffer hat unserem Wissen zufolge meist bessere Ergebnisse zu Folge:

http://www.nordiqc.org/Techniques/Epitope_retrieval.htm

Leider muss meisten auch der Permeabilisierungsschritt optimiert werden. So ist z.B. Saponin reversibel und sollte deshalb in allen Puffern verwendet werden während des Experiments.

Ich weiß, dass Sie viel Zeit für diese Experimente verwendet haben und möchte Ihnen daher ein neues Röhrchen oder einen Gutschein als Ersatz anbieten (vorausgesetzt, das Produkt wurde in den letztensechs Monatengekauft). Dafür benötige ich jedoch ihre ursprüngliche Bestellnummer und die Lotnummeroder einen Kontakt in Ihrer Einkaufsabteilung und das Datum der Bestellung. Würden Sie mir bitte zusammen mit diesen Informationen mitteilen, welche Alternative Sie bevorzugen?

Vielen Dank für Ihre Kooperation und Hilfsbereitschaft. Ich freue mich bald wieder von Ihnen zu hören.

Question

Hello Thank you for getting back to me, yes I would like a peptide for ab47329 made that would be great. I can not order it today as we finish for christmas and are back on the 5th january so I shall be in touch then. Can you tell me what the controls suggested are for and what to do with them Im not sure at the moment Thank you Kindest regards

Read More
Answer

Thank you for contacting us. Isotype controls are the primary antibodies that do not have specificity for any target. These can be used as negative control and are helpful in determining the background staining due to secondary antibodies. By comparing the result of actual primary antibody and isotyope control ab you may determine the target localization easily. No primary control also helps determining the background staining due to secondary antibodies. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
