Melanosomal Marker Antibodies
Melanosomes are organelles that synthesize, store, and transport melanin. They are found in skin melanocytes, choroidal melanocytes, retinal pigment epithelial cells, and in melanophores of lower vertebrates. Melanosomes can produce melanin when human skin is exposed to ultraviolet radiation, after which they are transferred from melanocytes to nearby keratinocytes.
While melanosomes are vital for protecting the skin from UV radiation, the means by which melanosomes move is not fully understood. Melanosomal marker antibodies detect proteins specific to melanosomes and can aid in the study of the stucture and function of melanosomes. Melanosomal marker antibodies can also help elucidate the role or roles a protein may play in a number of tasks that are centered in or influenced by the melanosome. Quality Invitrogen melanosomal marker antibodies are available for a variety of research needs.
