CD3 in Mouse Splenocytes.

CD3 was detected in immersion fixed mouse splenocytes using Rat Anti-Mouse CD3 Biotinylated Monoclonal Antibody (Catalog # BAM4841) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Streptavidin (yellow; Catalog # NL999) and counterstained with DAPI (blue).

Background: CD3

The T cell receptor (TCR)/CD3 complex consists of two variable antigen-recognition receptor chains (TCR-alpha/TCR-beta or TCR-gamma/TCR-delta) that are non-covalently linked to at least four different invariant chains: CD3 gamma, CD3 delta, CD3 epsilon, and the CD3 zeta chain that exists as either a homodimer or as a heterodimer with its splice-variant the CD3 eta chain. The CD3 complex functions to transduce intracellular signals during TCR antigen recognition. CD3 is expressed early in thymocyte development, and on a subset of NK cells. CD3 epsilon is one of at least three invariant proteins that associate with the variable antigen recognition chains of the T cell receptor and function in signal transduction.

FAQs for Mouse CD3 Biotinylated Antibody

Showing  1 - 1 of 1 FAQ Showing All
  • Q: What is the optimal working concentration of the antibody?

    A: Novus' product datasheets provide a recommended concentration for each validated application that is a starting point for titration. The concentration required will vary from lab to lab due to other variables and thus titration is strongly recommended for optimizing results.
