    ab108977 was shown to react with aRHGDIA in wild-type HEK293T cells in Western blot with loss of signal observed in ARHGDIA knockout cell line ab266447 (ARHGDIA knockout cell lysate ab257356). Wild-type HEK293T and ARHGDIA knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 5% milk in TBST for 1 hr before incubation with ab108977 overnight at 4 °C at a 1/1000 dilution. Blots were incubated with goat anti-rabbit HRP secondary antibodies at 0.2μg/mL before imaging.

Abcam and YCharOS are working together to help address the reproducibility crisis by enabling the life science community to better evaluate commercially available antibodies.

Question

The only purchase order number i can find is FMVS1125183, but i'm not sure
if this is an internal university number, or if it relates to Abcam's
system as well.
As of today's date (18th Sept 2012), the antibody is no longer in the
6-month guarantee period because of the protracted nature of this process,
however the drop in antibody quality did occur within the 6-month period.
Cheers,

Answer

Thank you for your email.

Unfortunately the order is out of Abpromise guarantee period. The order was placed on 17th January 2012, which means it was under 6 month guarantee period until 16th June however the complaint was submitted in August so I am sorry we will not be able to replace the product on this occasion. I would suggest contacting us within 6 month period for claiming the guarantee period.

We now have new lot of this product in stock. Please buy the new lot and use it as per your convenience, if in any case the product fails please let us know we will be happy to replace the product.

I hope this information is nevertheless helpful to you. Should you have any question please do not hesitate to contact me.

Question

I stored it in its original white-topped Abcam vial in my -20 degree
freezer along with my other antibody stocks. There was a slight drop in
quality with the antibody after about 4 months (using 1:5000 dilution), but
from about 5 months onwards it was a sudden drop off to no signal at all,
even at 1:1000.
Cheers,

Answer

Thanks you for your email. I apologize for the delay.

We unfortunately are unable to find reason why the activity of this antibody is dropping. Also we haven't received any other quality complaint for this antibody so I am sorry we will not be retesting this product at the moment.

To proceed further in this case; could you please provide the purchase order number? I assume that the product you have purchase is within 6 month guarantee period and might be eligible for replacement. If the product was purchased within 6 month guarantee period I will be happy replacing the product.

I will look forward to receiving the order number soon.

Answer

Thank you very much for sending the information.

In order to understand the problem better could you provide details how this antibody was stored?

Was the antibody degradation gradual or it just stopped working after 6 months?

Many thanks for your cooperation in advance. I will look forward to hearing from you soon.
