권장 분석 절차

This antibody has been tested by cell-surface immunofluorescent staining ( ≤8µg/million cells) with flow cytometric analysis to assure specificity and reactivity. Since the pTα is expressed at low density on the surface of immature thymocytes, we recommend the use of Mouse Fc Block™ (anti-mouse CD16/CD32 mAb 2.4G2, Cat. No. 553141/553142) and amplification of the staining intensity through the use of a biotinylated second-step antibody, such as anti-mouse IgG1 mAb A85-1 (Cat. No. 553441), followed by a "bright" third-step reagent, such as Streptavidin-PE (Cat. No. 554061).

제품 고시

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

2F5

At very early stages in the intrathymic differentiation of T lymphocytes which will bear αβ T Cell Receptors (TCR), the TCR β chain forms a heterodimer with the pre-TCR α chain (pTα) to form the pre-TCR. This pre-TCR associates with the signal-transducing CD3 complex and controls the survival and proliferation of CD4- CD8- (DN) thymocytes, plays a role in allelic exclusion of the TCR β chain, directly or indirectly regulates TCR δ chain expression, and is eventually replaced by the TCR α chain as thymocytes mature. The 2F5 monoclonal antibody specifically recognizes the PTα on the surface of CD44- CD25-/lo DN thymocytes.

Purified
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
