ANSWER: |
I'm very sorry to hear you are having problems with ab38. We do not have a recommended starting dilution so I would like to recommend trying a higher concentration of antibody (try 10ug/ml). We have only received one complaint regarding this popular antibody. I can certainly offer you a replacement vial of ab38 in case the antibody was damaged during transport, or a credit note or refund. I can also offer you a replacement vial of ab39 if you purchased this antibody in the last 90 days. If this is the case let me know the order details. Please let me know which you would prefer and I will arrange accordingly. I look forward to hearing from you,

Thank you for your prompt response. I have another question. I'd like to know how the staing is. The staing is clear nuclear staing or nuclear and cytoplasmic staing? |
|||||||||
ANSWER: |
Thanks again for your email. The staining should be nuclear. Please let me know if you have any more questions. |

I would like to confirm wether Cyclin A antibody [E67.1] is useful for IHC(paraffin) and to see the successful figure of IHC.
|
|||||||||
ANSWER: |
Thank you for your email. Yes, ab39 has been tested for application in IHC-Formalin-fixed paraffin-embedded sections. However, we unfortunately do not have an image to share at this time. If you have any additional questions, please do contact us again. |

Cells at stages in the cell cycle from quiescence to mitosis (1-8) were loaded onto SDSPAGE and blotted with anti CDK2 antibody. Note all cells have similar amounts of CDK2. In the lower panel these same extracts were first immunoprecipitated with anti Cyclin A monoclonal E67. In these lanes, only the CDK2 that is complexed to Cyclin A is immunoblotted. Note only the CDK2 in the later stages of the cell cycle is immunoprecipitated, which is when Cyclin A is made, This clearly shows that this antibody is able to immunoprecipitate cyclin A when it is bound to CDK2.
ab39 at a 1/100 dilution staining Cyclin A in African Green Monkey COS-7 cells by Immunocytochemistry/ Immunofluorescence.Cells were fixed in methanol and an Alexa-Fluor 555 conjugated anti-mouse secondary was used at a 1/3000 dilution.
