  • ab3105 staining CD90 / Thy1 in murine bone marrow cells (smeared directly onto glass slide) by Immunocytochemistry/ Immunofluorescence.
    Cells were fixed in paraformaldehyde, permeabilized using 0.5% saponin, blocked with 1% serum for 1 hour at 37°C and then incubated with ab3105 at a 1/300 dilution for 16 hours at 4°C. The secondary used was an Alexa-Fluor 546 conjugated goat anti-rat polyclonal used at a 1/400 dilution. Dapi stains nuclei in blue.

I can confirm that ab3105 was tested on formalin-fixed paraffin-embedded tissue sections from human reactive tonsil but we didn't detect signal with this antibody.

Thank you for contacting us. Abcam takes product quality seriously and we recently undertook an in-depth study examining storage conditions and antibody performance. After over 13,000 individual ELISA experiments, we have determined that storing our antibodies at various temperatures of up to 45°C for 1 week does not impact their activity. I would be happy to share a summary of our findings with you; please let me know if you would like to see this. As a precautionary measure only, we ship our antibodies in packaging with ice packs to provide extra temperature stability in transit. The ice pack may be thawed or even at room temperature when you receive it; please be assured that this is normal and that your product is safe to use. Once you have received the vial, please follow the long-term storage instructions on the datasheet. Our Abpromise to you is that, should our product not work as stated on the datasheet, we will resolve the issue to your satisfaction, either with helpful advice to optimize your experiment or a replacement or refund of the product. Please contact our knowledgeable Scientific Support staff should you experience any issues while using our products. Contact information can be found at: https://www.abcam.com/index.html?pageconfig=contactus I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information. PS: Attached is the tested data of few of our antibodies.

Thank you for your enquiry, we have not tested the antibody ab3105 in immunocytochemistry but the antibody is very likely to work as it works very well in perfusion fixed tissue and frozen post fixed tissue. I would definitely recommend fixing mouse cells prior to staining them, try ice cold 4% paraformaldehyde for 10,20,30min, and try also ice cold methanol 10min (or a combination of both). If your staining is still weak, make sure you have plenty of permabilising agent (tritonx100 0.3%v/v) in the antibody dilution buffer. If you still experience problems please do not hesitate to contact us again and provide us with a detailed protocol and we will investigate it into details to find out the root of the problem, I enclose a link to a form which will help you put together your protocol details easily, should you need our help: https://www.abcam.com/index.html?section=ihc&pageconfig=technical&intAbID=3105&mode=questionaire
