靶标

  • 功能

    Factor XIII is activated by thrombin and calcium ion to a transglutaminase that catalyzes the formation of gamma-glutamyl-epsilon-lysine cross-links between fibrin chains, thus stabilizing the fibrin clot. Also cross-link alpha-2-plasmin inhibitor, or fibronectin, to the alpha chains of fibrin.

  • 疾病相关

    Defects in F13A1 are the cause of factor XIII subunit A deficiency (FA13AD) [MIM:613225]. FA13AD is an autosomal recessive disorder characterized by a life-long bleeding tendency, impaired wound healing and spontaneous abortion in affected women.

  • 序列相似性

    Belongs to the transglutaminase superfamily. Transglutaminase family.

  • 翻译后修饰

    The activation peptide is released by thrombin.

  • 细胞定位

    Cytoplasm. Secreted. Secreted into the blood plasma. Cytoplasmic in most tissues, but also secreted in the blood plasma.

      ab4057 staining formalin fixed paraffin-embedded human bowel tumour tissue sections.  The sample was subjected to heat mediated antigen retrieval in citrate buffer (pH 6.0) and blocked with 10% srum for 1 hour at 24°C, prior to incubation with the primary antibody (diluted 1/100 in milk) for 12 hours at 4°C.  A biotinylated goat anti-rabbit antibody was used as the secondary.

    Question

    Thank you for your prompt reply. If you wouldn't mind, I have some more questions. I know that Factor VIII related antigen also stains endothelial cells. Can these 2 things be used interchangablely? It seems strange that we would be instructed to test Factor XIIIa on placenta. Is there something special about placental vessels?

    Answer

    Thank you for your enquiry. Both proteins are involved in the coagulation cascade. Whether you can use the antibodies interchangeably depends on the experiments you are doing. Unfortunately we aren't experts in the field, so we couldn't tell you which one would be better to use in your particular situation. I am not sure why placenta is suggested as the positive control. It is possible that the protein shows higher expression in placental blood vessels than vessels in other tissues. If you would like me to enquire further about this matter, I would be happy to. I hope this information helps, please do not hesitate to contact us if you need any more advice or information,

    Question

    The positive control listed for this antibody is placenta. Which placental cells should I use? In addition, the localization is listed as cytoplasmic and nuclear. Which localization gives more sensitive staining?

    Answer

    Thank you for your enquiry. Factor XIIIa is a coagulation protein present in the plasma. Staining is cytoplasmic. It should stain the endothelial cells of the blood vessels. It appears that the datasheet states that the cellular localization is cytoplasmic and secreted, not cytoplasmic and nuclear. I completely missed that, and I apologize. I hope this information helps. Please do not hesitate to contact us if you need anything further.

    Question

    No, i didn't try placenta due to the absence of this tissue in our laboratory. Placenta is also recommended as a positive control in the protocol provided by Novocastra. In addition to it, skin can be used as a positive control too since dermal dendritic cells are immunoreactive to Factor XIIIa AB (ref. Novocastra catalog) and upregulation of this cell type is well described in different inflammatory conditions. I hope this information is helpful

    Answer

    Thank you for your response. This antibody has been tested for IHC using human placenta so it would be very important to run an experiment with tested positive control alongside with the samples. As you have mentioned in your e-mail, dendritic cells also express Factor XIIIa. However, the expressed levels of Factor XIIIa may be different from that in the placenta which usually shows very high levels of this protein. We have looked through our order record and actually the batch number you received was 77421. We have sold many vials form this batch without any problem. It may well be that the vial you received has become inactivated during shipping and/or storage. We can offer you a new vial free of charge. Please do let us know if you are interested in, and then we can place a new order for you as soon as possible.

    Question

    I would like to use the AB in mouse. How likely is a crossreactivity with mouse FXIII?

    Answer

    Thank you for your enquiry. All the information we have on species cross reactivity is specified on the datasheet, these are updated as soon as any new information is brought to our attention. As far as we are aware, cross reactivity with mouse has not yet been tested for use with ab4057. Should you decide to go ahead and purchase this product, please let us know how you get on and in return we will forward a reward of your choice, typically an Amazon gift voucher. Please let me know if you require any further assistance.
