Immunogen
Synthesized peptide derived from the Internal region of human Reg IV.
Specificity
Reg IV Polyclonal Antibody detects endogenous levels of Reg IV protein.
Formulation
Liquid in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide.
Dilution rate
IHC: 1/100 - 1/300. ELISA: 1/40000.. IF 1:50-200
Purification process (Immunogen)
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen.
Background
function:May be involved in inflammatory and metaplastic responses of the gastrointestinal epithelium.,induction:Up-regulated by mucosal injury from active Crohn's disease or ulcerative colitis. Up-regulated in colorectal tumors. Up-regulated in epithelial cells at regenerating margins of peptic ulcers in the stomach and duodenum.,online information:Regenerating protein IV,similarity:Contains 1 C-type lectin domain.,tissue specificity:Highly expressed in the gastrointestinal tract including the duodenum, jejunum, ileum, ileocecum, appendix, descending colon, pancreas and small intestine. Weakly expressed in normal colon and stomach. Strongly expressed in most colorectal tumors than in normal colon. Preferentialy expressed in mucinous tumors and in some cases neuro-endocrine tumors. Expressed in mucus-secreting cells and enterocyte-like cells. In small intestine expressed at the basal perinuclear zone of goblet cells.,
