Pacific Blue™ Anti-mouse Ly-6A/E (Sca-1) Antibody
1140595 25 µg $90.00       
1140600 100 µg $190.00       
Clone: D7
Isotype: Rat IgG2a, κ
Reactivity: Mouse
Immunogen: IL-2-dependent mouse T-cell line (CTL-L)
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation: The antibody was purified by affinity chromatography, and conjugated with Pacific Blue™ under optimal conditions. The solution is free of unconjugated Pacific Blue™ .
Concentration: 0.5 mg/ml
Storage & Handling: The Ly-6A/E antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.
Application:

FC - Quality tested

Application Notes:

The D7 antibody has been reported to induce T cell activation and inhibit TCR-induced IL-2 production. Additional reported applications (for the relevant formats) include: Western blotting1,2, immunoprecipitation1, in vitro lymphocyte activation3-6, induction of redirected lysis7, induction of T cell inhibitory signalling8, immunofluorescence9, and immunohistochemical staining of acetone-fixed frozen sections13 and Bouin-fixed, paraffin-embedded samples9.

The two Sca-1 recognizing clones D7 and E13-161.7 have been shown to bind distinct epitopes due to the inability of D7 to block the binding of E13-161.7.14 

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. The suggested use of this reagent is ≤ 1.0 µg per 106 cells in 100 µl volume. It is highly recommended that the reagent be titrated for optimal performance for each application.

* Pacific Blue™ has a maximum emission of 455 nm when it is excited at 405 nm. Prior to using Pacific Blue™ conjugate for flow cytometric analysis, please verify your flow cytometer's capability of exciting and detecting the fluorochrome.

C57BL/6 mouse splenocytes stained with

C57BL/6 mouse splenocytes stained with Pacific Blue™ D7



Description:

Ly-6A/E, also known as Sca-1, is an 18 kD member of the Ly-6 multigene family. Ly6A/E is a glycosylphosphatidylinositol (GPI)-linked protein expressed on hematopoietic stem cells. In mice expressing the Ly-6.2 haplotype (e.g., AKR, C57BL, C57BR, DBA/2, SJL, SWR, and 129), Ly-6A/E is also expressed on peripheral B lymphocytes and thymic and peripheral T lymphocytes. Strains expressing the Ly-6.1 haplotype (e.g., BALB/c, CBA, C3H/He, DBA/1, and NZB) have low Ly-6A/E expression on resting peripheral lymphocytes. The expression of Ly-6A/E on lymphocytes is upregulated upon activation from both Ly6.1 and Ly6.2 haplotype mice. Ly-6A/E is thought to be involved in the regulation of both T and B cell responses.

Other Names: Sca-1
Structure: Ly-6 multigene family, 18 kD
Distribution: Hematopoietic stem cells, activated T cells and B cells, subset of resting B cells and T cells
Function: Regulates B and T cell responses
