Species Reactivity:
NB 400-105 reacts with human, hamster, rat and mouse ABCA1. Other species have not been tested.
Applications:
Uses:
NB400-105 may be used for Western blot, histochemical applications, and Flow Cytometry. For western analysis a band representing ABCA1 is seen at ~220 kDa. Additional non-specific bands are seen at lower molecular weights, but do not interfere with the ABCA1 signal. Other applications have been reported in literature using this antibody including immunofluorescence, immunohistochemistry, flow cytometry, and immunocytochemistry. NOTE: It is important not to boil the sample before loading onto a gel. Boiling can cause aggregation in large proteins, resulting in the proteins inability to enter the gel.
Dilutions:
Flow Cytometry, Immunocytochemistry, Immunofluorescence, Immunohistochemistry-Paraffin 1:200, Immunoprecipitation, Western Blot 1:500

Mutations in the ABCA1 gene (ATP-binding cassette transporter 1) have been reported in Tangier disease (TD). TD is an autosomal recessive disorder characterized by an absence of plasma HDL, cholesterol ester depositing in the reticulo-endothelial system and deviations in cellular lipid trafficking. ABCA1 mediates the apo-A1 associated export of cholesterol and phospholipids from the cell. It is expressed on the plasma membrane and the Golgi complex, and is regulated by cholesterol flux. Regulation of the cholesterol flux between HDL and macrophages is competitive between ABCA1 and SR-BI.
