Product Overview
This rabbit polyclonal antibody targets GPI-anchor transamidase component PIGS in human and rat samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 61.7 kDa, and the supplier reports an observed band at about 65 kDa.
PIGS is a subunit of the GPI transamidase complex in the endoplasmic reticulum, which attaches a preassembled glycosylphosphatidylinositol (GPI) anchor to newly made proteins. Loss of PIGS function impairs GPI-anchored protein expression and has been linked to inherited GPI biosynthesis disorders.

Immunogen
Recombinant human PIGS fragment (Arg184–Asp504), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human and rat. UniProt places GPI-anchor transamidase component PIGS in the endoplasmic reticulum membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
