Application Notes
Western Blot band representing ABCA1 is observed at approx. 220 kDa. Additional non-specific bands are seen at lower molecular weights, but do not interfere with the ABCA1 signal. In Simple Western only 10-15 uL of the recommended dilution is used per data point.

Theoretical MW
220 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Background

ATP-binding cassette transporter A1 (ABCA1) is a cAMP-dependent and sulfonylurea-sensitive anion transporter belonging to the ATP-binding cassette family. ABCA1 is involved in the regulation of apolipoprotein AI (apoAI)-mediated cholesterol efflux and high-density lipoproteins (HDL) metabolism (1). In the brain, ABCA1 transports cholesterol to apoE, the major CNS apolipoprotein, where it influences motor function and synaptic morphology.

ABCA1 is comprised of 2,261 amino acids with a theoretical molecular weight of 254 kDa and human ABCA1 shares 97% amino acid identity with mouse ABCA1. The general structure of ABCA consists of two transmembrane domains (TMDs) and two nucleotide binding domains (NBDs). ABCA1 is a widely distributed cell-membrane protein with the highest expression found in macrophages. DHHC8 mediated palmitoylation of ABCA1 is essential for its localization to the plasma membrane and expression of mouse ABCA1 (not human) is induced by cAMP analogs (2). ABCA1 is phosphorylated at Ser1042 and Ser2054 by PKA, with Ser2054 being key for regulating phospholipid efflux. Mutations in ABCA1 have been linked to atherosclerosis and the progression of metabolic syndrome phenotypes: high density lipoprotein deficiency type 1 (HDLD1); also known as Tangier disease (TGD), and high density lipoprotein deficiency type 2 (HDLD2); also known as familial hypoalphalipoproteinemia (FHA) (3).

FAQs for ABCA1 Antibody (NB400-105). (Showing 1 - 10 of 12 FAQs).

  1. For Western blot protocol for ABCA1 antibody NB400-105, why does it suggest treating with beta-ME while not heating?
    • For some membrane proteins it is not recommended to boil the samples. You may incubate them at room temperature or at 37C in SDS sample buffer with BME. However, from personal experience, if you boil the samples you will not see the protein on the blot. I do not think the exact reason is known.
  2. Do you have a protocol for Flow cytometry analysis with this ABCA1 antibody (NB400-105)?
    • Please see this link to our protocol for Flow cytometry. This is a general protocol that our lab uses as a guideline.
  3. We purchased this antibody a few weeks ago, and we by mistake stored it at -20 degrees Celsius. Is there possible the antibody still works?
    • Most likely the antibody should still work, but we cannot guarantee it. The biggest thing with antibody storage in most cases, especially for unconjugated antibodies, will be to avoid freeze/thaw cycles as much as possible. So even with ones that we recommend to freeze long term we still recommend aliquoting so they can go through as few of those as possible. I would say since it will probably only undergo one when you move it back to 4 degrees Celsius you should be fine, but again I can't say with 100% certainty. If you have a problem with detection using this product, please let us know so that we can figure out other possibilities to help you in that situation.
  4. I am interested in looking at this marker on monocytes by flow cytometry. I noticed that a directly conjugated 488 ab is available, and that your flow cytometry protocol calls for methanol fixation of the cells. Is the fixation required for antibody binding, or may it be used on cells that have not been methanol fixed? I would like to retain other markers.
    • Methanol is not required for antibody binding, but it is a fixation method that we found to not interfere with the antibody-antigen binding. You may use unfixed cells, but you may not be able to achieve staining. If you fix your cells with a formaldehyde-based fixative (we recommend antigen retrieval for IHC). However, as an inter-membrane protein, you will need to permeabilize your cells in order for the antibody to access the protein.
  5. To do Western blot for the determination of ABCA1 protein level, do I need to order NB400-105 or NB400-105B? Which one do you recommend if we also order the secondary antibody catalog # NB730-H?
    • The difference between NB400-105 or NB400-105B is biotin conjugation. It is up to you whether you would like to order the primary antibody that is conjugated or not. With the biotin-conjugated antibody (catalog # NB400-105B), you won't need a secondary, just a (strept)avidin-labelled detection reagent, such as streptavidin-HRP. With the unconjugated primary (catalog # NB400-105), you will need to use a secondary antibody. Some people say that when you use the secondary, there is an amplification of signal, because more than one secondary can bind to each primary. However, with the directly conjugated antibody you have fewer reagents and fewer wash steps.
  6. We purchased NB400-105, Lot# Z5, but the datasheet (approx. 450kDa) was differ from your website (approx. 220kDa) for size of WB. Which molecular weight is correct?
    • ABCA1 is highly glycosylated and has a predicted molecular weight of approximately 250 kDa without post-translational modification. The apparent molecular weight will change based on treatment and sample. All of the images on our website and datasheet are correct.
  7. Does this product contain any BSA?
    • No, this antibody does not have any BSA in its formulation.
  8. I bought ABCA1 antibody (NB400-105) from your company recently and used it in Flow cytometry. I want to know the binding site of ABCA1 and the antibody; is it within the cell or outside? Also, do I need to change the cytomembrane's permeabilization before my test?
    • The immuogen region of NB400-105 is within residues 1100-1300 of human ABCA1 and as a result it does not cover the extracellular domains, as a consequence, permeabilization is required for this antibody. As a general guideline, we usually recommend using 0.5-1.0% Triton detergent in the buffers in order to allow full permeabilization of our antibody.
  9. Is post-nuclear lysate is necessary? Can't I lysate my cells with RIPAbuffer (#R0278 sigma)?
    • The post-nuclear lysate you mentioned is posted on our website to demonstrate how we do the experiments, and how it was done by our collaborator (Ref Link #1). The procedure of getting the post-nuclear lysate was just for removing the nuclei before lysis and therefore the cleaner the lysates would be. You do not need to follow the method for the experiment that led to the result.
  10. Why shouldn't I boil the samples? is it OK to boil them if using RIPAbuffer?
    • To fractionate a membrane-bound protein, the lipid moieties associated with the protein frequently cause the smearing or streaky appearance of our WB. To result this difficulty, it is advised that we resuspend cell pellets in the SDS-sample buffer, left at room temp without boiling, spinning down the viscous cell debris, and then subject to PAGE and blotting. And this was the reason we suggested you not to boil your protein samples. Whether it will work for resuspending cell pellets in RIPA buffer, unfortunately we have no such data.
