Alternate Names for Niemann-Pick type C1 Like-1 Antibody

  • Niemann-Pick C1-like protein 1
  • NPC1 (Niemann-Pick disease, type C1, gene)-like 1
  • NPC11L1


Dietary consumption and intestinal cholesterol absorption contribute to plasma cholesterol levels, which factor into the risk of coronary heart disease. Niemann-Pick type C1 Like 1 protein (NPC1L1 or NPC3) is enriched in the small intestine and is found in the brush border membrane of enterocytes. It plays a critical role in absorption of intestinal cholesterol.

FAQs for Niemann-Pick type C1 Like-1 Antibody (NB400-128). (Showing 1 - 2 of 2 FAQs).

  1. I am currently working with samples from pigs and wants to investigate the cholesterol transporter NPC1L1 by Western blot. For pig, I could not find a specific antibody, so I look for a sequence homology with the pig. Can you give me information on the antigens of the following antibodies: Niemann-Pick type C1 Like-1 Antibody NB400-127 and NB400-128?
    • I ran a blast on the human protein and the pig protein and there is 80% homology between the two proteins. Our lab only recommends using if the percentage homology is 85% or above. You may wish to test either antibody and you would be eligble for our Innovators Reward Program in which you would gain a 50% refund on the product and a 50% discount on another product. All you would need to do is email your results, (successful or unsuccesful) to The amino acid range for the immunogen for NB400-127 is 1000-1100 amino acids and that for NB400-128 is 500- 600.
  2. Can I please get the epitope of your NB400-128?
    • The exact sequence of this product is proprietary, but I can provide you with the amino acid range. It was made to an internal region of rat Niemann-Pick type C1 Like-1 (between residues 500-600). [UniProt# Q6T3U3].
