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:

Thank you for contacting us.

I do hope the suggestions made today shed some light upon the issue you are experiencing with ab24102 Anti-MRP1 antibody [MRPm5] and look forward to hear the results.

This product is covered by our Abpromise guarantee. If we cannot remedy this issue and this is a product that you have purchased within the last six months, we will replace or refund it under our Abpromise guarantee, as you are using it according to specifications listed on our datasheet.

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.
https://www.abcam.com/index.html?datasheet=29889 https://www.abcam.com/index.html?datasheet=29889.
MRP4 is barely detectable in liver and therefore I recommend to use ab30304 (Prostate (Human) Tissue Lysate - adult normal tissue) as positive control.
https://www.abcam.com/index.html?datasheet=30304 https://www.abcam.com/index.html?datasheet=30304.
With ab63907 we used ab29745 (Placenta (Human) Tissue Lysate - adult normal tissue) successfully as control.

The only recommendation I have seen for a western blot positive control is a lysate from cells transfected with MRP1. We do not have such a lysate or a recombinant protein. As I mentioned in our phone call, endogenous sources include lung, testis, and peripheral mononuclear cells. I searched the literature for a cell line that might be a suitable positive control (we have many lysates) and found this article: Cloning and Characterization of the Murine and Rat mrp1 Promoter Regions Mol Pharmacol. 2003 Nov;64(5):1259-69. which mentions HL60/ADR and H69AR, which we do not have. The article may suggest other potential candidates. I hope this helps. If you have any other questions, please do not hesitate to contact us.
