Kifunensine is an immunoactive compound originally produced by Kitasatosporia kifunense, which displays competitive inhibition against immunosuppressive factor in tumor-bearing mice. Kifunensine has also been shown to be a potent inhibitor of the purified glycoprotein processing enzyme, mannosidase I (MAN1), specifically MAN1A1, MAN1A2, MAN1B1 and MAN1C1. Enzymes of this class are important factors for the biosynthesis of various types of N-linked oligosaccharide structures. Inhibition of these structures by kifunensine can interfere with cell-to-cell adhesion, targeting of lysosomal hydrolases to lysosomes, and clearance of asialoglycoproteins from the serum.

How much Kifunensine to use in cell culture? I don't know how much to add into a cell culture plate with 2ml of media.

Asked by: Jz28sail
Thank you for your question. This product has not been specifically tested for cell culture use and is not cell culture grade. However, most products can still be used in cell culture applications by following basic cell culture protocols, e.g. using cell culture grade/sterilized solvents, aseptic technique, and sterile filtering in a sterile hood. I provided a couple of references below: Pubmed ID: 21795794 Pubmed ID: 2144287 If you have any further questions or concerns, please feel free to contact our Technical Service department by calling 800-457-3801 option 2, emailing, or using the Live Chat function on our website.

Rated 5 out of 5 by from scientific researcher Very useful for studying ER glycosylation trimming events!

Rated 5 out of 5 by from Hosokawa Hosokawa, et. al. (PubMed ID 17727818) found that kifunensine completely inhibits mannose trimming from NHK in mock transfected cells (HEK293). It also greatly diminishes in cells that have been transfected to over-express Golgi 1,2-mannosidase. -SCBT Publication Review
