  • 特异性

    Studies have shown tyrosinase to be a very specific marker for melanomas, not cross reacting with any other tumors or normal tissues tested Other studies have shown tyrosinase to be a more sensitive marker when compared to HMB-45 and MART-1. It has also shown to label a higher percentage of desmoplastic melanomas than HMB-45. However, both tyrosinase and MART-1 negative staining was seen in those variants without an epidermal component. Unlike HMB-45, neither tyrosinase or MART-1 discriminates between activated or resting melanocytes. In conclusion, tyrosinase appears to be a superior melanoma marker when compared to HMB-45.

靶标

  • 功能

    This is a copper-containing oxidase that functions in the formation of pigments such as melanins and other polyphenolic compounds. Catalyzes the rate-limiting conversions of tyrosine to DOPA, DOPA to DOPA-quinone and possibly 5,6-dihydroxyindole to indole-5,6 quinone.

  • 疾病相关

    Defects in TYR are the cause of albinism oculocutaneous type 1A (OCA1A) [MIM:203100]; also known as tyrosinase negative oculocutaneous albinism. An autosomal recessive disorder in which the biosynthesis of melanin pigment is absent in skin, hair, and eyes. It is characterized by complete lack of tyrosinase activity due to production of an inactive enzyme. Patients present with a life-long absence of melanin pigment after birth, and manifest increased sensitivity to ultraviolet radiation with predisposition to skin cancer. Visual anomalies include decreased acuity, nystagmus, strabismus and photophobia.
    Defects in TYR are the cause of albinism oculocutaneous type 1B (OCA1B) [MIM:606952]; also known as albinism yellow mutant type. An autosomal recessive disorder in which the biosynthesis of melanin pigment is reduced in skin, hair, and eyes. It is characterized by partial lack of tyrosinase activity. Patients have white hair at birth that rapidly turns yellow or blond. They manifest the development of minimal-to-moderate amounts of cutaneous and ocular pigment. Some patients may have with white hair in the warmer areas (scalp and axilla) and progressively darker hair in the cooler areas (extremities). This variant phenotype is due to a loss of tyrosinase activity above 35-37 degrees C.

    Question

    I would like to enquire about recombinant controls for antibodies I recently purchased from you. Are there any recombinant controls or alternative controls for western blotting for the following antibodies; ab738 ab22601 ab1872 ab23798

    Read More
    Answer

    Thank you for your email. Below I have listed some suggestions for controls to use with these antibodies. If you have any additional questions, please contact Ab23798 - We do sell recombinant Il-1 beta, it is catalog numbers ab9617, ab9723, and ab9788. Also, the antibody clearly stains IL1b positive cells in liver, spleen, pituitary and brain of endotoxin treated rats, so those tissues can be used as a positive control as well. Ab1872 - Placenta is recommended as a positive control. Also, caspase 1 is expressed in larger amounts in spleen and lung. Also found in liver, heart, skeletal muscle, kidney and testis. No expression in the brain. Ab738 - Melanoma is recommended as a positive control. Ab22601 - I couldn't find much information except for this: Msx2 mRNA is found expressed at higher levels in immature tumors, including a yolk sac tumor, seminoma, and chroiocarcinoma, and also in various tumors of epithelial origin. The gene expression is frequently activated in carcinoma derived cell lines.

    Question

    Your spec-sheet for tyrosinase antibody (ab738) does not have any information for western blotting. I would like to know at what size the band comes out, and how much I need to dilute the antibody for western blotting. And what kind of western protocol would you recommend me using, milk based? BSA-based? Or other ? I would appreciate your prompt response.

    Answer

    Thank you for your enquiry regarding ab738 and its use in WB. It has been reported in the literature that this clone T311 works in western however we have not tested it ourselves, I apologise for the inconvenience. We would recommend doing a preliminary experiment to determine the optimal dilution (a range of dilutions should be tried e.g 1:50-1:500) and we usually recommend to try BSA 5% in TBST (1hr, RT or 4C) for blocking. Please do not hesitate to contact us if you need any more advice or information or have any problems with your experiment,
