purity :
Antigen-specific Affinity Chromatography.
form :
Supplied as solution form in PBS, pH7.4, containing 0.02% NaN3, 50% glycerol.
storage stability :
Store at 4 degree C for frequent use. Stored at -20 degree C to -80 degree C in a manual defrost freezer for one year without detectable loss of activity. Avoid repeated freeze-thaw cycles. Stability Test: The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37 degree C for 48h, and no obvious degradation and precipitation were observed.The loss rate is less than 5% within the expiration date under appropriate storage condition.
tested application :
Immunohistochemistry (IHC), Immunocytochemistry (ICC), Immunofluorescence (IF), Western Blot (WB), ELISA
app notes :
Western blotting: 0.5-2ug/ml. Immunocytochemistry in formalin fixed cells: 5-20ug/ml. Immunohistochemistry in formalin fixed frozen section: 5-20ug/ml. Immunohistochemistry in paraffin section: 5-20ug/ml. Enzyme-linked Immunosorbent Assay: 0.05-2ug/ml. Optimal working dilutions must be determined by end user.

ncbi summary :
receptor for intrinsic factor (IF)-cobalamin; involved in vitamin B12 uptake (cyanocobalamin) [RGD, Feb 2006]
uniprot summary :
CUBN: Cotransporter which plays a role in lipoprotein, vitamin and iron metabolism, by facilitating their uptake. Binds to ALB, MB, Kappa and lambda-light chains, TF, hemoglobin, GC, SCGB1A1, APOA1, high density lipoprotein, and the GIF-cobalamin complex. The binding of all ligands requires calcium. Serves as important transporter in several absorptive epithelia, including intestine, renal proximal tubules and embryonic yolk sac. Interaction with LRP2 mediates its trafficking throughout vesicles and facilitates the uptake of specific ligands like GC, hemoglobin, ALB, TF and SCGB1A1. Interaction with AMN controls its trafficking to the plasma membrane and facilitates endocytosis of ligands. May play an important role in the development of the peri-implantation embryo through internalization of APOA1 and cholesterol. Binds to LGALS3 at the maternal-fetal interface. Defects in CUBN are a cause of recessive hereditary megaloblastic anemia 1 (RH-MGA1); also known as MGA1 Norwegian type or Imerslund-Grasbeck syndrome (I-GS). RH-MGA1 is due to selective malabsorption of vitamin B12. Defects in vitamin B12 absorption lead to impaired function of thymidine synthase. As a consequence DNA synthesis is interrupted. Rapidly dividing cells involved in erythropoiesis are particularly affected.
