- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
The microsomal triglyceride transfer protein (MTP) catalyzes the transport of triglyceride, cholesteryl ester, and phospholipid between membranes within the lumen of microsomes in hepatocytes and enterocytes. MTP forms a heterodimer with the 58 kDa protein disulfide isomerase. PDI catalyzes the isomerization of intramolecular disulfide bridges, thereby allowing them to generate their most thermodynamically stable configuration within proteins. MTP is mutated in abetalipoproteinemia, which results from defects in apolipoprotein-B (apoB)-containing lipoproteins. A lack of MTP expression prevents secretion of apoB from mammalian cells, leading to intracellular degradation. In the C-terminal region, MTP has structural homology to apoB and the lamprey lipovitellin protein. This region contains a membrane binding helix (Helix A), and a triglyceride binding helix (Helix B). Mutations in Helix B cause abetalipoproteinemia. In addition, inhibitors of MTP activity may be important therapeutics for lowering atherogenic lipoprotein levels. Thus, MTP is a microsomal protein that is required for transport of lipids between membranes in liver and small intestines.
