Scientific Data Images for Human Melan-A/MART-1 Antibody

Detection of Human Melan-A/MART-1 antibody by Western Blot.

Detection of Human Melan-A/MART-1 by Western Blot.

Western blot shows lysates of SK-Mel-28 human malignant melanoma cell line. PVDF membrane was probed with 0.5 µg/mL of Sheep Anti-Human Melan-A/ MART-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8008) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Melan-A/MART-1 at approximately 18-20 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of Human Melan-A/MART-1 antibody by Simple WesternTM.

Detection of Human Melan-A/MART-1 by Simple WesternTM.

Simple Western lane view shows lysates of SK-Mel-28 human malignant melanoma cell line, loaded at 0.2 mg/mL. A specific band was detected for Melan-A/MART-1 at approximately 21 kDa (as indicated) using 5 µg/mL of Sheep Anti-Human Melan-A/MART-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8008) followed by 1:50 dilution of HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: Melan-A/MART-1

Melan-A (MeLANoma-A; also MART-1, LB39-AA and SK29-AA, MLANA) is a 18-24 kDa member of a melanocyte lineage-specific, generally structurally-unrelated family of proteins. It is expressed only in melanocytes, retinal pigment epithelium and melanoma cells. Melan-A is involved in melanosome formation, and appears to stabilize both GPCR143/OA-1 and PMEL, thus ensuring the formation of a stage 2 (melanin production within a fibrillar matrix) melanosome. It is typically found in the Golgi, and upon inversion of its topology, becomes embedded in the ER. It may also appear in endosomes and on the cell surface where, in theory, it is recognizable by a special naïve type of CD8+ T cell that is derived from the thymus. Notably, these cells normally appear to be unresponsive, even in the face of exposure to skin melanocytes during wound healing. Human MLANA is a 118 amino acid (aa) type III (no signal sequence) transmembrane protein. It contains a 26 aa extracellular region (aa 1-26), and a 71 aa cytoplasmic domain (aa 48-118). There is one utilized phosphorylation site at Ser108, and the molecule is known to undergo acylation, creating a MW of 23-34 kDa in SDS-PAGE. Over aa 52-118, human Melan-A shares 62% aa sequence identity with mouse MLANA.
