Description

General description

The melanocyte-specific protein PMEL (also known as Pmel17, gp100, melanocyte protein, premelanosome protein or silver locus protein homolog (SILV) is a type I transmembrane glycoprotein that is expressed primarily in pigment cells of the eye and skin. In melanosomes, PMEL protein forms a fibrillar matrix on which the UV-shielding pigment melanin is deposited.1-2

Specificity

Monoclonal Anti-PMEL antibody specifically recognizes human PMEL protein.

Application

The antibody may be used in various immunochemical techniques including Immunoblotting (~100 kDa), Immunohistochemistry and Immunofluorescence.

Biochem/physiol Actions

PMEL fibrils are a major functional component of the melanosomal compartment as they optimize the melanin polymerization, condensation and storage.1,3
In addition, PMEL fibrils have an amyloidogenic nature sharing features with pathological amyloids.4 Thus, PMEL is suggested as an excellent model system to study mechanisms of intracellular amyloid formation.1
Mutations in PMEL are associated with pigmentation disorders and/or impairments in eye development in various species.1,5,6

Physical form

Supplied as a solution in 0.01 M phosphate buffered saline pH 7.4, containing 15 mM sodium azide as a preservative.

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.
