Product Information
Product Usage Information
This product is the carrier free version of product #55546. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol.
This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN or CUT&Tag assays. If you require a carrier free formulation for chromatin profiling, please contact us. Optimal dilutions/concentrations should be determined by the end user.
BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity.

Storage
Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance.
Specificity / Sensitivity
FcRn (E9J8W) Rabbit mAb (BSA and Azide Free) recognizes endogenous levels of total FcRn protein.
Species Reactivity:
Human
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly250 of human FcRn protein.
Background
The neonatal Fc receptor, FcRn, is an atypical Fc gamma receptor that bears homology to class I MHC (major histocompatibility complex) and associates with β2-microglobulin (1). FcRn is expressed by the vascular endothelium, several epithelial cell types, and hematopoietic cells including several innate immune cell types and B cells (2). FcRn mediates recycling and transcytosis of IgG, resulting in protection of IgG from catabolism and an extended serum half-life of IgG relative to other antibody isotypes (3). In addition, FcRn transports IgG across the placenta and also mediates uptake of maternal IgG from milk, resulting in enhanced humoral immunity in the fetus and neonates (1,4,5). FcRn also plays an important role in initiation of adaptive immunity by transporting immune complexes to intracellular dendritic cell compartments for antigen processing and presentation to T cells (6-8). In addition to IgG, FcRn also binds albumin and similarly protects it from catabolism, leading to extended half-life and high plasma concentrations (9).
