		Technical Data
S0630-05A	Secretory Component Glycoprotein (Secretory Component p85, Extracellular matrix protein 1, ECM1, ECM-1, Epithelial Transport Receptor)

Description:
Secretory Component Glycoprotein is an epithelial transport receptor for polymeric IgA and IgM. Antibody to secretory component has been shown to be useful for identifying glandular carcinomas. Defects in Secretory Component Glycoprotein are the cause of lipoid proteinosis (LiP), also known as lipoid proteinosis of Urbach and Wiethe or hyalinosis cutis et mucosae. LiP is a rare autosomal recessive disorder characterized by generalized thickening of skin, mucosae and certain viscera. Classical features include beaded eyelid papules and laryngeal infiltration leading to hoarseness. Histologically, there is widespread deposition of hyaline material and disruption/reduplication of basement membrane.

Applications:
Suitable for use in Western Blot, Immunoprecipitation and Immunohistochemistry. Other applications not tested.

Recommended Dilutions:
Western Blot: 1:1000
Immunoprecipitation: 1:50
Immunohistochemistry (Frozen, paraffin): 1:200
Optimal dilutions to be determined by the researcher.
