  • Function
    The CD3 complex mediates signal transduction.
  • Involvement in disease
    Defects in CD3D are a cause of severe combined immunodeficiency autosomal recessive T-cell-negative/B-cell-positive/NK-cell-positive (T(-)/B(+)/NK(+) SCID) [MIM:608971]. A form of severe combined immunodeficiency (SCID), a genetically and clinically heterogeneous group of rare congenital disorders characterized by impairment of both humoral and cell-mediated immunity, leukopenia, and low or absent antibody levels. Patients present in infancy recurrent, persistent infections by opportunistic organisms. The common characteristic of all types of SCID is absence of T-cell-mediated cellular immunity due to a defect in T-cell development.

Thank you for contacting us.

We currently do not offer products which meet each of the requirements that you have set. I assembled for you well characterized products which meet most of these requirements but each has some deficiency. Pricing is to be found near the top of the webpage for each product directly below the bold type face product name. There is not currently any special pricing at JHMI. Each datasheet contains all images which we currently have for the products. Any publications which we are aware of the product being used in are located behind the specific references tab or at the bottom of the page.

I would recommend rabbit antibodies as it appears you want to test in mouse however I have added mouse antibodies should you wish to use a mouse on mouse IHC kit such as theMouse on Mouse (M.O.M) Polymer IHC Kit ab127055:https://www.abcam.com/Mouse-on-Mouse-MOM-Polymer-IHC-Kit-ab127055.html

Unconjugated anti-CD3 that targets rat, mouse and pig produced in any animal:

For UNTESTED species and/or applications, we have established a testing discount program. Here is a brief description of how it works:

The testing discount program is for customers who like to use an antibody/protein on an untested species/application. You would purchase the antibody at full price, test it and submit an Abreview with your data (positive or negative). On your next order you will receive a discount for ONE antibody at the full price (100%) of the antibody you have tested. The terms and conditions applicable to this offer can be found here: https://www.abcam.com/index.html?pageconfig=resource&rid=11998&viapagetrap=collaborationdiscount

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
