  • Function
    May be involved in the control of the cell cycle at the G1/S (start) and G2/M (mitosis) transitions. May primarily function in the control of the germline meiotic cell cycle and additionally in the control of mitotic cell cycle in some somatic cells.
  • Tissue specificity
    Very high levels in testis and very low levels in brain. Also found in myeloid Leukemia cell lines.
  • Sequence similarities
    Belongs to the cyclin family. Cyclin AB subfamily.
  • Developmental stage
    Expression increases in early G1 phase and reaches highest levels during the S and G2/M phases.

  • All lanes : Anti-Cyclin A1 antibody (ab53699) at 1/500 dilution

    Lane 1 : SKOV3 cell extract
    Lane 2 : SKOV3 cell extract with immunising peptide

    Predicted band size: 52 kDa
    Observed band size: 55 kDa
    why is the actual band size different from the predicted?

  • ICC/IF image of ab53699 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab53699, 1µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

  • IHC image of ab53699 staining in Human Breast cancer formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab53699, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Thank you very much for confirming the details.

We are unsure about the identity of bands. Not many complaints are received for this antibody infact this is the second since December 2011 so protocol troubleshooting might help.

There is onepoint you may consider; the heavy and light chains of IP antibody. If rabbit antibody is used for IPing then you might observe 25, 55 kDa band corresponding to light and heavy chains however the band 80 kDa and 100 kDa is just not relevant what we should expect from this ab and in WB. So please check the antibody used for IP.

Secondly, It seems that you are Co-IPing the cyclin A1/ A2 with your protein of interest so the problem might be with the co-Ip procedure. I would suggest using whole hela cell lysates as positive control. If the whole cell lysates is already used (as ab input) then there is a band at 55 kda in 30 minutes exposure image which I presume is cyclin A1. If the whole lysates has notbeen used so I would suggest trying these also.

I am sure the above recommendations will be helpful. If however the results do not improves please contact me I will send you a replacement product.

Have a good weekend!

Thanks you very much for your email. I am very sorry to hear that you are experiencing problems with this antibody.

I have checked the image and details you have kindly provided and in order to know more about the problem I have following questions;

- Could you fill the protocol details in the attached questionnaire?
- What is the name of cell line used?
- How the lysates was prepared? What sort of lysis buffer was used? Have you added any protease inhibitor in lysis buffer?
- Have you used the ab38 with IP lysate of ab70335? Could you please explain, how the IP lysate of ab70335 is compatible with ab38?
- Is it true both ab38 and ab70335 were used with same IP lysate?

Please send the details to us asap. Should you have any question please do not hesitate to contact me.
