靶标

  • 功能

    Plays a central role in the biogenesis of melanosomes. Involved in the maturation of melanosomes from stage I to II. The transition from stage I melanosomes to stage II melanosomes involves an elongation of the vesicle, and the appearance within of distinct fibrillar structures. Release of the soluble form, ME20-S, could protect tumor cells from antibody mediated immunity.

  • 组织特异性

    Preferentially expressed in melanomas. Some expression was found in dysplastic nevi. Not found in normal tissues nor in carcinomas. Normally expressed at low levels in quiescent adult melanocytes but overexpressed by proliferating neonatal melanocytes and during tumor growth.

  • 序列相似性

    Belongs to the PMEL/NMB family.
    Contains 1 PKD domain.

  • 结构域

    The RPT domain is essential for the generation of the fibrillar matrix of melanosomes.
    The lumenal domain is necessary for correct processing and trafficking to melanosomes.

  • 翻译后修饰

    A small amount of P1/P100 (major form) undergoes glycosylation to yield P2/P120 (minor form). P2 is cleaved by a furin-like proprotein convertase (PC) in a pH-dependent manner in a post-Golgi, prelysosomal compartment into two disulfide-linked subunits: a large lumenal subunit, M-alpha/ME20-S, and an integral membrane subunit, M-beta. Despite cleavage, only a small fraction of M-alpha is secreted, whereas most M-alpha and M-beta remain associated with each other intracellularly. M-alpha is further processed to M-alpha N and M-alpha C. M-alpha C further undergoes processing to yield M-alpha C1 and M-alpha C3 (M-alpha C2 in the case of PMEL17-is or PMEL17-ls). Formation of intralumenal fibrils in the melanosomes requires the formation of M-alpha that becomes incorporated into the fibrils. Stage II melanosomes harbor only Golgi-modified Pmel17 fragments that are derived from M-alpha and that bear sialylated O-linked oligosaccharides.
    N-glycosylated. O-glycosylated; contains sialic acid.

  • 细胞定位

    Secreted and Endoplasmic reticulum membrane. Golgi apparatus. Melanosome. Endosome > multivesicular body. Identified by mass spectrometry in melanosome fractions from stage I to stage IV. Localizes predominantly to intralumenal vesicles (ILVs) within multivesicular bodies. Associates with ILVs found within the lumen of premelanosomes and melanosomes and particularly in compartments that serve as precursors to the striated stage II premelanosomes.

      ab787 staining Melanoma in the human Melanoma cell line WM3248 xenopraph by IHC-P (formaldehyde-fixed paraffin-embedded sections). Tissue samples were fixed with formaldehyde; permeabilized with 0.1% Triton X-100 and blocked with 100% Dakocytomation X0909 for 1 hour at room temperature; antigen retrival was by heat mediation in Citric buffer (pH6). The sample was incubated with primary antibody (1/25) at 4°C for 18 hours. An HRP-conjugated Goat polyclonal to mouse IgG (1/100) was used as secondary antibody.

      Overlay histogram showing Malme-3 cells stained with ab787 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab787, 1/10 dilution) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells ) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in Malme-3 cells fixed with 4% paraformaldehyde (10 min)/permeabilized in 0.1% PBS-Tween used under the same conditions.

    Answer



    We don't have strict guidelines for length of storage for antibodies. In general, for antibody products stored at 4 degrees C, we would expect them to be stable for at least one year from date of purchase.

    Merci de nous avoir contactés; ma collègue m'a fait part de votre appel.

    Je suis heureux de savoir que l'anticorps a finalement fonctionné en cytométrie en flux. J'ai compris que vous deviez utiliser beaucoup d'anticorps pour obtenir des résultats satisfaisants sur 300.000 cellules. J'ai donc mis en place l'envoi d'une unité gratuite d'ab787 pour que vous puissiez terminer vos travaux avec cet anticorps.

    Question

    Product code: 787
    Inquiry: Hi, I'm looking at this product: Anti-Melanoma antibody [HMB45] (ab787) Do you have a protein/peptide that this antibody recognizes? I need to use the protein/peptide in my experiment as a positive control. Otherwise, are you able to recommend an antibody/antigen pair that can be used in this way? It doesn't have to be HMB45 strictly any human melanoma marker will do. I've been looking also at S100 in your catalog but I don't know which antibodies/proteins are compatible. Thanks.

    Read More
    Answer

    Thank you for contacting us.

    Unfortunately, the blocking peptide for ab787 antibody is not available for purchase. We have ˜25 anti melanoma antibodies available but we do not have antigen available for any one of these however if you could select few as per your requirement then I will check with our collaborator laboratory if they can supply the peptide as special request.

    We do have antibody / antigen pair for S100 protein. Please check the catalogue number ab14688 and ab30380.

    I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
