Function

cAMP-dependent and sulfonylurea-sensitive anion transporter. Key gatekeeper influencing intracellular cholesterol transport.
Tissue specificity

Widely expressed, but most abundant in macrophages.
Involvement in disease

Defects in ABCA1 are a cause of high density lipoprotein deficiency type 1 (HDLD1) [MIM:205400]; also known as analphalipoproteinemia or Tangier disease (TGD). HDLD1 is a recessive disorder characterized by absence of high density lipoprotein (HDL) cholesterol from plasma, accumulation of cholesteryl esters, premature coronary artery disease (CAD), hepatosplenomegaly, recurrent peripheral neuropathy and progressive muscle wasting and weakness.
Defects in ABCA1 are a cause of high density lipoprotein deficiency type 2 (HDLD2) [MIM:604091]; also known as familial hypoalphalipoproteinemia (FHA). HDLD2 is inherited as autosomal dominant trait. It is characterized by moderately low HDL cholesterol, predilection toward premature coronary artery disease (CAD) and a reduction in cellular cholesterol efflux.
Sequence similarities

Belongs to the ABC transporter superfamily. ABCA family.
Contains 2 ABC transporter domains.
Domain

Multifunctional polypeptide with two homologous halves, each containing an hydrophobic membrane-anchoring domain and an ATP binding cassette (ABC) domain.
Post-translational
modifications

Phosphorylation on Ser-2054 regulates phospholipid efflux.
Palmitoylation by DHHC8 is essential for membrane localization.
Cellular localization

Membrane.

Exposure time: 4 minutes

Abcam recommends using milk as the blocking agent. This blot was produced using a 3-8% Tris Acetate gel under the TA buffer system. The gel was run at 150V for 60 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 3% Milk before being incubated with ab66217 overnight at 4°C. Antibody binding was detected using an anti-mouse antibody conjugated to HRP, and visualised using ECL development solution.
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-ABCA1 antibody [HJ1] (ab66217)

ab66217 (4µg/ml) staining ABCA1 in human liver using an automated system (DAKO Autostainer Plus). Using this protocol there is moderate cell membrane staining throughout the liver parenchyma.
Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer EDTA pH 9.0 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-ABCA1 antibody [HJ1] (ab66217)

IHC image of ABCA1 staining in human liver formalin fixed paraffin embedded tissue section, performed on a Leica Bond^TM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab66217, 0.2µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
Flow Cytometry - Anti-ABCA1 antibody [HJ1] (ab66217)

Overlay histogram showing HepG2 cells stained with ab66217 (red line). The cells were fixed with methanol (5 min) and incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab66217, 2µg/1x10⁶ cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG2b [PLPV219] (ab91366, 2µg/1x10⁶ cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a decreased signal in HepG2 cells fixed with 4% paraformaldehyde (10 min) used under the same conditions.

Please note that Abcam does not have data for use of this antibody on non-fixed cells. We welcome any customer feedback.

Question

Thank you for your kind replacement of the antibody! I was able to test it on human prostate cancer cell line PC3 lysed with RIPA buffer (last lane of the samples indicated by arrow) and my other prostate cancer cell lines prepared before. The membrane was first detected with your new antibody and then reprobed with FASN. As you can see from the images, your new antibody can only show a low molecular weight background band. FASN antibody clearly detects the target protein with several non-specific bands. The pictures in two different pages represents different exposure time. Therefore, I am afraid that your new antibody does not work either. If you can provide a positive control, I am willing to repeat experiment again. If your positive control works, it means that your antibodies work. I am happy to keep them and improve my sample preparation.

Asked on Jan 08 2013

Answer

Yes, I can send you as a one time exception a positive control lysate (rat liver (ab29413), https://www.abcam.com/liver-rat-whole-cell-lysate-normal-tissue-ab29413.html). This has been tested with ab66217 and gave strong bands.

Also I would suggest to check the gel after transfer as some of the high MW proteins might have not completely transfered onto the membrane. You can check this by staining the gel with Coomassie Blue. if you see bands in the gel at 200 kDa and higher, you might want to adjust your transfer conditions so that all high MW protein are being transfered.

Also, avoid boiling of your samples before loading them onto the gel. Warming your sample to 50-60 degree Celsius is sufficient for denaturation in loading buffer.

Again, FASN is a cytoplasmic protein and such is much easier to work with than ABCA1 which is very hydrophobic, glycosylated and of high MW.

Asked on Nov 23 2011

Answer

Thank you for submitting your recent review of ab66217. We are sorry to see that the results were unsatisfactory. I'd like to follow up with you to offer a couple of suggestions that may help improve these results. However we do fully guarantee this antibody to work in tested species and applications, so I would be happy to replace this antibody or issue a credit or refund if you would prefer. Some lower molecular weight bands are often seen with ABCA1 antibodies, and though the identity is not known, it is possible that these are cleavage fragments. Since the molecular weight of the full length ABCA1 is around 254 kDa, and this protein is heavily glycosylated, it might be difficult to transfer to the membrane. Did you do a Ponceau stain to verify the transfer? There are a few protocol alterations that we recommend when transfering such a large protein: 1) 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. Lowering methanol in the transfer buffer also promotes swelling of the gel, allowing large proteins to transfer more easily. We recommend 10% with nitrocellulose or none if using a PVDF membrane. 2) Choose wet transfer overnight at 4°C instead of semi-dry transfer. I look forward to hearing from you. If you would like a replacement, credit, or refund, please send me your order number and I will be happy to arrange this for you.
