Scientific Data Images for ABCA1 Antibody (1276B) - BSA Free

Western Blot: ABCA1 Antibody (1276B) [NBP2-54792] - Mouse Raw264.7 and human THP-1 cells were treated with and without the LXR agonist TO901317 (1 uM) for 24 hours. Total protein was then separated on a 12% gel by SDS-PAGE, transferred to PVDF membrane and blocked in 5% non-fat milk in TBST. The membrane was probed with 0.5 ug/ml anti-ABCA1 in 5% non-fat milk in TBST and detected with an anti-rabbit HRP secondary antibody using chemiluminescence.
Immunohistochemistry-Paraffin: ABCA1 Antibody (1276B) [NBP2-54792] - Analysis of a FFPE tissue section of mouse liver using ABCA1 antibody (1276B) Lot ckjv02 at 1:100 dilution. The primary antibody bound to ABCA1 antigen in the tissue section was detected using a HRP labeled secondary antibody and DAB reagent. Nuclei of the cells were counterstained with hematoxylin. This ABCA1 antibody generated specific staining in the membranes of the hepatocytes and the Kupffer cells. As expected for ABCA1, the staining signal was stronger in the Kupffer cells which are the tissue macrophages in liver.
Immunocytochemistry/Immunofluorescence: ABCA1 Antibody (1276B) [NBP2-54792] - HepG2 cells were fixed for 10 minutes using 10% formalin and then permeabilized for 5 minutes using 1X TBS + 0.5% Triton X-100. The cells were incubated with anti-ABCA1 at 10 ug/ml overnight at 4C and detected with an anti-rabbit DyLight 488 (Green) at a 1:500 dilution. Alpha tubulin (DM1A) NB100-690 was used as a co-stain at a 1:1000 dilution and detected with an anti-mouse DyLight 550 (Red) at a 1:500 dilution. Nuclei were counterstained with DAPI (Blue). Cells were imaged using a 40X objective.

Background: ABCA1

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).
