Background Information

SLC19A1, also named as RFC (reduced folate carrier), is an anionic exchanger that involved in the regulation of intracellular concentrations of folate in exchange for anions. The predicted MW of  SLC19A1 is 65 kDa and 25958-1-AP antibody recognizes the 46 kDa protein which is similar to papers. The 38-40 kDa minor forms and 58 kDa form have also been reported that could be alternate splicing, post-transcriptional modification or the role of accessory proteins. (PMID: 17404734, 9111015)
