Applications

Our Abpromise guarantee covers the use of ab18180 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P 1/200. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
ICC/IF Use at an assay dependent concentration.
Flow Cyt Use 1-2µg for 106 cells.

ab170190 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.
WB 1/200 - 1/500. Predicted molecular weight: 254 kDa.

Abcam recommends using BSA as the blocking agent and 80-100 ug of lysate.
ELISA Use at an assay dependent concentration.

Direct ELISA, where a 96-well plate was coated with recombinant ABCA1 C-terminal protein. The antibody was then added to the wells and a goat anti-mouse IgG HRP conjugate was used for colour development. For ABCA1 quantification, a pair of anti-ABCA1 antibodies should be used to formulate a Sandwich ELISA and with a presence of an ABCA1 protein Standard. Optimal dilution to be determined by the end user.

Target

  • 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.

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.

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.

Question

I saw that you changed the pictures from WB of ABAC1 in your datasheet. As you know I didn´t find the protein at , the actual, predicted molecular weigth of 220Kda of the previous 294Kda. My question is, the lower band at +|- 60Kda ( you also found) is correlated with the upper band? The size of the bands are correlated for the same condition?

Read More
Answer

In this image the lower band is actin which has been recognized by and anti-actin antibody. This has been used as a loading control to normalize the levels of protein detected by confirming that protein loading is the same across the gel. The expression levels of the loading control should not vary between the different sample lanes.
