    靶标

    • 功能

      Anchors the extracellular matrix to the cytoskeleton via F-actin. Ligand for dystroglycan. Component of the dystrophin-associated glycoprotein complex which accumulates at the neuromuscular junction (NMJ) and at a variety of synapses in the peripheral and central nervous systems and has a structural function in stabilizing the sarcolemma. Also implicated in signaling events and synaptic transmission.

    • 组织特异性

      Expressed in muscle fibers accumulating in the costameres of myoplasm at the sarcolemma. Expressed in brain, muscle, kidney, lung and testis. Isoform 5 is expressed in heart, brain, liver, testis and hepatoma cells. Most tissues contain transcripts of multiple isoforms, however only isoform 5 is detected in heart and liver.

    • 疾病相关

      Defects in DMD are the cause of Duchenne muscular dystrophy (DMD) [MIM:310200]. DMD is the most common form of muscular dystrophy; a sex-linked recessive disorder. It typically presents in boys aged 3 to 7 year as proximal muscle weakness causing waddling gait, toe-walking, lordosis, frequent falls, and difficulty in standing up and climbing up stairs. The pelvic girdle is affected first, then the shoulder girdle. Progression is steady and most patients are confined to a wheelchair by age of 10 or 12. Flexion contractures and scoliosis ultimately occur. About 50% of patients have a lower IQ than their genetic expectations would suggest. There is no treatment.
      Defects in DMD are the cause of Becker muscular dystrophy (BMD) [MIM:300376]. BMD resembles DMD in hereditary and clinical features but is later in onset and more benign.
      Defects in DMD are a cause of cardiomyopathy dilated X-linked type 3B (CMD3B) [MIM:302045]; also known as X-linked dilated cardiomyopathy (XLCM). Dilated cardiomyopathy is a disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death.

      Question


      In the diagnostic field, it is important to know which antibody is against to the carboxyl, the NH2 or the rod domain. However, It is not clear to me and to some customers (because I reviewed the answers posted in the website) the bunch of antibodies you offer are directed to.

      It is mentioned they share reactivity to the transmembrane part or are associated or share affinity to the other dystrophin associated proteins, but specifically the question is not answered.

      I wonder if you do not mind, to explain me the specific affinity of the antibody (rod, NH2, COOH domains) the antibodies are directed.

      Answer

      Thank you for your inquiry.


      Based on its primary structure, the dystrophin can be divided into four distinct structural domains: (1) the N-terminal actin-binding domain (aa 14-240), (2) the large triple helical spectrin-like domain (aa 253-3040) composed of 24 repeating units similar to those in β-spectrin, which are predicted to form triple-helical coiled-coils, (3) the cysteine-rich domain (aa 3080- 3360) and the C-terminal domain (aa 3361- 3685). http://www.sciencedirect.com/science/article/pii/0092867488903832

      ab7163 - Anti-Dystrophin antibody [MANDYS8]

      This antibody Monoclonal Anti-Dystrophin, clone MANDYS8, recognizes an epitope located on the rod domain of the human dystrophin molecule, The publications that are cited in the data sheet, which mapped the epitope that the MANDYS8 clone recognises are:

      1. Nguyen, thi Man, et al., FEBS Lett., 262, 237 (1990).
      2. Sedgwick, S., et al. Rapid mapping by transposon mutagenesis of epitopes on the muscular dystrophy protein, dystrophin Nucl. Acids Res. (1991) 19(21): 5889-5894


      According to these references the epitope recognised by this clone lies between residues 1400 and 1505.

      Regarding the epitopes of the other 3 antibodies, ab3149, ab7164, ab15277 - no information is available regarding yet. As soon as we have further details, we will update the corresponding datasheets.

      I hope that this helps and please do not hesitate to contact us if you require any further information or assistance.

      Question

      I get staining in my cells when treated with the primary antibody but no secondary antibody.

      Read More
      Answer

      Thank you for your phone call. As we discussed, this antibody is not conjugated so it should not produce any signal in the absence of a secondary antibody. It is likely that the signal you are observing is autofluorescence. The attached reference details several common types of autofluorescence and tips for avoiding them. I hope this helps, please let me know if you have any additional questions.

      Question

      Thank you for your very efficient dealingwith my concern regarding the nNOS antibody (see below) for frozen tissue sections. We did get in exchange the otherantibody I had referred to, and it is working both for frozen sections and western blots. The MHC II antibody for western blots, that wepurchased around the same time, also worked very well. So, we will continue orderingthese antibodies.

      However,we have a serious problem now with the dystrophin antibody MANDRA1, ab7164 which you advertise for western blots.In our hands, itdid not work for about 80 ug protein from myofibers in wild type mouse skeletal muscle homogenates, where MHC II is working very fine, even with 0.5 ug protein.

      I would like touse what we paid for the MANDRA1 (ab7164) as a credit for testing an alternative antibody. I have identified ab15277 (rabbit polyclonal) as of potential interest, even if no western blot is shown (although the recommended dilution is 1/100), because it seems to be widely used. The alternative seems to be ab3149 (mouse monoclonal). It does show a nice band, but it does not tell whether it isfrom a skeletal muscle extract, what amount of protein and what antibody dilution.

      Can you please e-mail me to advise on any of these or alternative antibodies for mouse dystrophin in western blot of skeletal muscle homogenates. I would like to talk to you on the phone.

      Question

      Thank you for the information, but the problem is that I want to stain cultured cells instead of sections. Unlike these papers were the authors use cryosections, I have to fix the cells with something. Is this possible? and which fixative do you recommend? Regards,

      Read More
      Answer

      Thank you for your e-mail. I would recommend using the same fixative that have been used in the references where staining was done on frozen section; unfortunately I cannot access those papers myself to find this information. I would suspect the fixation will be ice cold acetone or methanol (or a mixture) for 10min, so something similar would be a good starting point. If you have enough cells I would recommend trying in parallel a well with 4%PFA fixing (for 10min) just in case this works in ICC. I hope this will help you, could you please let me know how you get on and do not hesitate to contact me if you need further advice on your staining protocol,

      Question

      I'm interested in the ab7164 mandra-1 dystrophin antibody. However, I've one question, this is written in the datasheet 'The epitope recognized by the antibody is sensitive to formalin fixation and paraffin embedding'. I want to use this antibody on fixed cells and wonder if pfa fixation is suitable in this case. If not, what do you recommend me?

      Answer

      Thank you for your enquiry. The antibody will work in frozen sections and I would recommend the following references as sources of staining protocols as they have tested the antibody in IHC: Ellis JM et al.
