  • Function

    Ligand for multiple Notch receptors and involved in the mediation of Notch signaling. May be involved in cell-fate decisions during hematopoiesis. Seems to be involved in early and late stages of mammalian cardiovascular development. Inhibits myoblast differentiation (By similarity). Enhances fibroblast growth factor-induced angiogenesis (in vitro).
  • Tissue specificity

    Widely expressed in adult and fetal tissues. In cervix epithelium expressed in undifferentiated subcolumnar reserve cells and squamous metaplasia. Expression is up-regulated in cervical squamous cell carcinoma. Expressed in bone marrow cell line HS-27a which supports the long-term maintenance of immature progenitor cells.
  • Involvement in disease

    Defects in JAG1 are the cause of Alagille syndrome type 1 (ALGS1) [MIM:118450]. Alagille syndrome is an autosomal dominant multisystem disorder defined clinically by hepatic bile duct paucity and cholestasis in association with cardiac, skeletal, and ophthalmologic manifestations. There are characteristic facial features and less frequent clinical involvement of the renal and vascular systems.
    Defects in JAG1 are a cause of tetralogy of Fallot (TOF) [MIM:187500]. TOF is a congenital heart anomaly which consists of pulmonary stenosis, ventricular septal defect, dextroposition of the aorta (aorta is on the right side instead of the left) and hypertrophy of the right ventricle. This condition results in a blue baby at birth due to inadequate oxygenation. Surgical correction is emergent.
  • Sequence similarities

    Contains 1 DSL domain.
    Contains 15 EGF-like domains.
  • Developmental stage

    Expressed in 32-52 days embryos in the distal cardiac outflow tract and pulmonary artery, major arteries, portal vein, optic vesicle, otocyst, branchial arches, metanephros, pancreas, mesocardium, around the major bronchial branches, and in the neural tube.

Thank you for taking the time to contact us. I am sorry to hear you have had difficulty obtaining satisfactory results from the Anti-Jagged1 antibody (ab7771) .

I would like to reassure you that this antibody is tested and covered by our 6 month guarantee for the applications IHC-FoFr, ICC/IF, IHC-P, WB, IHC-Fr with mouse and human samples. In the event that a product is not functioning in the tested applications and species cited on the product data sheet, we will be pleased to provide a credit note, free of charge replacement or refund.

I would like to investigate this particular case further for you, and also obtain more information for our quality monitoring records. In order to proceed with this, I have enclosed a technical questionnaire below. I would appreciate if you could complete this. It will help you put the information we require together very easily. If I understood you right you have had problems in obtaining good results in WB? At the end of this email I attached the WB questionnaire. If you had problems with another application please let me know and I will send you the suitable questionnaire.

I would appreciate if you could also provide the image in another format. Regrettably I am not able to open it .

Thank you for your time and cooperation. We look forward to receiving the completed questionnaire.

I have heard back for the supplying lab.

The IHC data we have on the datasheet were contributed by their endusers. Unfortunately, they do not have a specific protocol available and all conditions must be user optimized.

I am sorry to not have more detailed information in that regard.

However, our in-house IHC-P protocol can be found here:

I hope that this will be of help.

Thank you for your reply and the image.

In the image I am not quite able to tell where the nuclei or potential plasma membranes are as there is no reference point. Does the image reflect just 1 cell or a line up of cells?
Would you have an image with DAPI staining of the nuclei (or any other counter stain) together with the Jagged1 staining? That would help a lot at least to know where the cells are located.

Here is the link to the Human protein Atlas for Jagged1
for the subcellular localization this link shows you in green where the protein is localized:

I have not yet heard back from the lab and will follow up with them as well.

I look forward to hear back from you.

Thank you for contacting us.

I am checking with the lab regarding the protocol, but could you please send me in the meantime an image showing the staining you are obtaining?

I look forward to your reply and helping you further.
