  • 描述

    小鼠单克隆抗体[OC125] to MUC16

  • 宿主

    Mouse

  • 特异性

    Studies have show that this antibody reacts with approximately 80% of epithelial ovarian neoplasms of serous, endometrioid, clear cell and undifferentiated types. No reactivity has been shown for mucinous ovarian tumors or in germ cell or hematopoietic tumors. It reacts with both normal tissues and neoplasms of fallopian tube, endometrium, endocervix and mesothelioma. It does not react with colon cancer. Normal tissues such as breast, liver, skin, kidney and spleen are negative.

靶标

  • 功能

    Thought to provide a protective, lubricating barrier against particles and infectious agents at mucosal surfaces.

  • 组织特异性

    Expressed in corneal and conjunctival epithelia (at protein level). Overexpressed in ovarian carcinomas and ovarian low malignant potential (LMP) tumors as compared to the expression in normal ovarian tissue and ovarian adenomas.

  • 序列相似性

    Contains 2 ANK repeats.
    Contains 56 SEA domains.

  • 结构域

    Composed of three domains, a Ser-, Thr-rich N-terminal domain, a repeated domain containing more than 60 partially conserved tandem repeats of 156 amino acids each (AAs 12061-21862) and a C-terminal transmembrane contain domain with a short cytoplasmic tail.

  • 翻译后修饰

    Heavily O-glycosylated; expresses both type 1 and type 2 core glycans.
    Heavily N-glycosylated; expresses primarily high mannose and complex bisecting type N-linked glycans.
    May be phosphorylated. Phosphorylation of the intracellular C-terminal domain may induce proteolytic cleavage and the liberation of the extracellular domain into the extracellular space.
    May contain numerous disulfide bridges. Association of several molecules of the secreted form may occur through interchain disulfide bridges providing an extraordinarily large gel-like matrix in the extracellular space or in the lumen of secretory ducts.

  • 细胞定位

    Cell membrane. Secreted > extracellular space. May be liberated into the extracellular space following the phosphorylation of the intracellular C-terminus which induces the proteolytic cleavage and liberation of the extracellular domain.

      Overlay histogram showing HeLa (human epithelial cell line from cervix adenocarcinoma) cells stained with ab693 (red line). The cells were fixed with 80% methanol (5 minutes) and then permeabilized with 0.1% PBS-Tween for 20 minutes. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab693, 1 µg/1x106 cells) for 30 minutes at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 minutes at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2 µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HeLa cells fixed with 4% paraformaldehyde (10 minutes)/permeabilized with 0.1% PBS-Tween for 20 minutes used under the same conditions.

    Question

    I am inquiring about the antigen peptide about the anti-MUC16 antibody [OC125] (ab693). I am now studying the structure and function of MUC16. If I could know in which region this antibody could recognize the protein, it will be a great help for my study.

    Answer

    Thank you for your interest in the MUC16 antibody, clone OC125. The papers from 1981 and 1983 that are listed in the references section of the ab693 datasheet describe production and characterization of the antibody. The antigen was not a peptide; it was a cell line, OVCA433, established from a patient with cystadenocarcinoma. (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC370929/?page=2) The location of the epitope that the antibody recognizes has not, to our knowledge, been determined.

    Question

    Could you give me information about concentration of MAB, α-hu OC125 (α-hu Muc16). A F/P-ratio would be likewise available?

    Read More
    Answer

    The IgG concentration of the lot you have is 25.5 ug/mL. The antibody is not conjugated, so there is no F/P ratio.

    Question

    He needs this produkt to storting with FACS and he has to do life staining.

    He need this cells to grow

    Read More
    Answer

    Thank you for your reply and for clarifying the questions.

    I can confirm that both these antibodies (ab693 and ab134093) are tested and covered by our 6 month guarantee for flow cytometry.

    However, I am sorry they have not been tried and tested for FACS cell sorting where live cells are required, so regrettably we would not be able to guarantee how well this will work. Both contain low concentration of preservative which may affect the cell viability.

    I hope this will be helpful. If you have any further questions, please do not hesitate to contact me.
