folate receptor
1.Objective: To study folate-conjugated albumin nanoparticles targeting to tumor cells via folate receptor-mediated endocytosis.
3.The soluble FBP are found in serum, cerebrospid fluid and cytoplasma, called as sFR, but membrane-associated FBP, which are found in various types of cells, are divited into two kinds , folate receptor(FR) and reduced folate carrier(RFC) in recently. FR have a high-affinity to folic acid and RFC have a more-affinity to reduced folate compounds, such as 5-formyltetrahydrofolate and MTX.
