GPI8 Antibody (C-term)

Purified Rabbit Polyclonal Antibody (Pab)

  • WB - GPI8 Antibody (C-term) AP2462b
    The anti-GPI8 Pab (Cat. #AP2462b) is used in Western blot to detect GPI8 in mouse liver tissue lysate.
  • IHC-P - GPI8 Antibody (C-term) AP2462b
    Formalin-fixed and paraffin-embedded human cancer tissue reacted with the primary antibody, which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated. BC = breast carcinoma; HC = hepatocarcinoma.

Target/Specificity This GPI8 antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 266-297 amino acids from the C-terminal region of human GPI8.
Dilution WB~~1:1000
Format Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is prepared by Saturated Ammonium Sulfate (SAS) precipitation followed by dialysis against PBS.
StorageMaintain refrigerated at 2-8°C for up to 2 weeks. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.
PrecautionsGPI8 Antibody (C-term) is for research use only and not for use in diagnostic or therapeutic procedures.
Protein Information
Synonyms GPI8
Function Mediates GPI anchoring in the endoplasmic reticulum, by replacing a protein's C-terminal GPI attachment signal peptide with a pre-assembled GPI. During this transamidation reaction, the GPI transamidase forms a carbonyl intermediate with the substrate protein.
Cellular Location Endoplasmic reticulum membrane; Single-pass type I membrane protein

GPI8 is a member of the cysteine protease family C13 that is involved in glycosylphosphatidylinositol (GPI)-anchor biosynthesis. The GPI-anchor is a glycolipid found on many blood cells and serves to anchor proteins to the cell surface. This protein is a member of the multisubunit enzyme, GPI transamidase and is thought to be its enzymatic component. GPI transamidase mediates GPI anchoring in the endoplasmic reticulum, by catalyzing the transfer of fully assembled GPI units to proteins.
