    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 38 kDa
    Observed band size: 50 kDa
    why is the actual band size different from the predicted?
    Additional bands at: 35 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 30 seconds

    LRG1/LRG contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted.

Customer reviews and Q&As


Thank you for your reply.

I have had a look at all the anti-LRG1 antibodies we have to see if any of them might be able to pick up this difference in glycosylation.

The only one I would suggest might be worth trying is the ab63836. This immunogen used to raise this antibody does cover the region with the glycosylation site 37, however, there is no knowing whether the antibody detects this precise region or not.

Alternatively, the ab105312 covers the region 35-84 of LRG1 and may therefore be able to pick up the glycosylation at 37 or 79, however as it is a rabbit polyclonal (as is ab63836), it may be that there are a mixture of antibodies, detecting different epitopes.

Could you detect the glycosylation by treating the sample with enzymes to remove the glycosylation and performing a western blotting comparing the sample with unteated sample (there shouldbe a shift in size of the bands)?

I hope this information has been of help. If you have any further questions, please do not hesitate to contact us again.
