General description

Conserved oligomeric Golgi complex 8 (COG8), also known as DOR1 or CDG2H, is a member of the conserved oligomeric Golgi (COG) complex. COG complex is composed of eight distinct subunits organized as heterotrimeric groups namely Cog2-Cog3-Cog4 and Cog5-Cog6-Cog7. They are interlinked by the dimeric group comprising Cog1 and Cog8.

Specificity

Anti-COG8 (C-terminal) recognizes human COG8.

Immunogen

synthetic peptide corresponding to the C-terminal region of human COG8, conjugated to KLH

Application

Anti-COG8 (C-terminal) antibody produced in rabbit may be used in:
  • immunoblotting
  • immunoprecipitation
  • immunofluorescence

Biochem/physiol Actions

COG complex, is an evolutionarily conserved multi-subunit protein complex that regulates membrane trafficking and maintenance of Golgi glycosylation machinery in eukaryotic cells. Mutations in the COG8 gene cause congenital disorder of glycosylation, type IIh, a disease that is characterized by under-glycosylated serum proteins, and whose symptoms include severe psychomotor retardation, failure to thrive, seizures, and dairy and wheat product intolerance.

Physical form

Solution in 0.01 M phosphate buffered saline pH 7.4, containing 15 mM sodium azide

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage freeze in working aliquots. Repeated freezing and thawing is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.
