Anti-MRP1 antibody [MRPm5] (ab24102)

I'm assuming you're referring to a lysis buffer for sample preparation prior to western blot. If this is the case, since MRP1 is a membrane bound protein we recommend using RIPA buffer for lysis. Our 10X RIPA buffer ab156034 is through the link below:

Our sample preparation guide below is helpful if you have lysis buffer questions for other protein targets:

I have found some additional information about large protein transfer which may also be of help to you. The following information is from our Western Blot guide and may be found at: https://www.abcam.com/index.html?pageconfig=resource&rid=11404

Note on transfer of large and small proteins
The balance of SDS and methanol in the transfer buffer, protein size, and gel percentage can affect transfer efficiency. The following modifications will encourage efficient transfer.
Large proteins (>100 kD)
For large proteins, transfer out of the gel may be very slow, just as they run slowly within the gel during separation. If blotting a large protein, be sure to run your samples in a low-concentration gel, 8% or less. These will be very fragile, so handle carefully.
Large proteins will tend to precipitate in the gel, hindering transfer. Adding SDS to a final concentration of 0.1% in the transfer buffer will discourage this. Methanol tends to remove SDS from proteins, so reducing the methanol percentage to 10% or less will also guard against precipitation.
Lowering methanol in the transfer buffer also promotes swelling of the gel, allowing large proteins to transfer more easily.
Methanol is only necessary if using nitrocellulose. If using PVDF, methanol can be removed from the transfer buffer altogether, and is only needed to activate the PVDF before assembling the gel/membrane sandwich.
Choose wet transfer overnight at 4°C instead of semi-dry transfer.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for your inquiry. I am happy to confirm that all these products are suitable for WB and tested and guaranteed.
I suggest ab29889 (Liver (Human) Tissue Lysate - adult normal tissue) as positive control for ab3366, ab3373, ab3375 and ab24102.

MRP4 is barely detectable in liver and therefore I recommend to use ab30304 (Prostate (Human) Tissue Lysate - adult normal tissue) as positive control.

With ab63907 we used ab29745 (Placenta (Human) Tissue Lysate - adult normal tissue) successfully as control.

Thank you for contacting Abcam. We offer a number of PGP antibodies that are guaranteed to work in Flow Cytometry on dog cells. I would recommend https://www.abcam.com/CD44-antibody-IM7-ab119863.htmlor the FITC conjugated https://www.abcam.com/CD44-antibody-IM7-FITC-ab19622.htmlantibodies. I've pasted the link to the search results below: https://www.abcam.com/index.html?pageconfig=searchresults If you also require a MRP1 antibody that works in Flow Cytometry we offer ab24102 Anti-MRP1 antibody [MRPm5] ( https://www.abcam.com/MRP1-antibody-MRPm5-ab24102.html). This has not yet been tested in dog and would not therefore to covered by our Abpromise.
