Background Information

TGN46 (TGOLN2), the human homologue of rat Tgn38, is a transmembrane glycoprotein predominantly localized to the TGN (trans-Golgi network). TGN is a major secretory pathway sorting station for proteins and lipids. TGN46 may be involved in regulating membrane traffic to and from TGN. Alternatively spliced transcript variants encode different TGN46 isoforms. TGN46 has an apparent molecular mass of 100-150 kDa, suggesting extensive O- and N-glycosylations.

Thomas (Verified Customer) (09-18-2020)

HEK293T cells were fixed in 4% PFA for 15 mins and permeabilised in 0.1% Triton-X 100 in PBS. Cells were blocked in 1% BSA. Primary antibody solution was diluted at 1:200 in blocking solution and incubated for 1 hour. Goat anti-rabbit 647 Alexa Fluor secondary antibody (1:250 - red) and DAPI (1:2000 - blue) were incubated with cells for 1 hour.
