Question (57250) | Recombinant Human CARHSP1 protein (ab116535)

Go to datasheet (ab116535)


Thank you very much for finding an HA-tagged protein (CARHSPI,ab116535) for me in your catalogue. I've looked at the data sheet and it sounds ideal, as its concentration is known and it is a good size for running on Westerns. My colleagues and I are developing expression systems for foreign proteins in the algal chloroplast, so it would be very useful to be able to visually quantify the HA-tagged foreign proteins without having to purify them every time.

As the product is quite expensive, I was wondering if it's possible to get a free sample that I could test out before ordering? I would like to check that it runs as a single band and that the concentration and buffer are suitable for our SDS-PAGE conditions. If it gives good results we would hope to adopt this protein as the quantification standard for all our HA western blots.

Many thanks for your assistance,


Thank you very much for your interest in ab116535.

Unfortunately we do not have aliquots of our products in stock which we can send out for testing purposes. However I would be pleased to make you the following offer: We do not currently have an image of ab116535 in Western blot. Therefore, I can offer a discount off a future purchase if you buy ab116535 now, use itWestern blotand submit your results with an image to us in the form of an Abreview. The discount would be to the value of 1 free protein (or the value of ab116535 off another product).

It doesn’t matter whether the result is positive or negative, we would just really like to receive your feedback. So even if the protein is not suitable for Western blot, you would receive the value of the protein off another product.
