Application Notes
This Niemann-Pick type C1 Like-1 antibody is useful for Immunohistochemistry paraffin embedded sections and Western blot. In Western blot a band is observed at ~140 kDa representing NPC1L1, and a nonspecific band may be observed at ~45 kDa depending on the lysate used. Use in Electron Microscopy reported in scientific literature (PMID: 21051527).
Theoretical MW
140 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.

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 (NB400-127). (Showing 1 - 1 of 1 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.
