Ly-6A/E (Sca-1) Antibody — Figure 3. Reduced frequencies of T cell progenitors in Fermt3 -/- thymi. ( A ) Thymocytes from Fermt3 +/+ and Fermt3 -/- mice were stained for lineage markers (B220, CD19, TER119, NK1.1, CD11b, Gr-1, CD8alpha, CD3e, TCRbeta, TCRgammadelta and CD11c), CD44 and c-kit to identify DN 1-2 (Lin neg , c-kit hi , CD44 hi ) and the DN 3-4 (Lin neg , c-kit low , CD44 low ) populations. ( B and C ) PB from Fermt3 +/+ and Fermt3 -/- animals ( P3 ) were stained for lineage markers (TER119, B220, CD11b, Gr-1, CD11c, NK1.1, CD4 and CD8alpha), c-kit and Sca-1 to identify hematopoietic progenitor cells and analysed by flow cytometry. N = 4. Numbers within the representative FACS plots indicate cell percentages. Bars indicate means +- standard errors. **p < 0.01; ***p < 0.001. See also Figure 3--figure supplement 1 .

Thymocytes from Fermt3 +/+ and Fermt3 -/- P3 mice were stained for lineage markers (B220, CD19, TER119, NK1.1, CD11b, Gr-1, CD8alpha, CD3epsilon, TCRbeta, TCRgammadelta and CD11c), CD44 and CD25 to identify and quantify DN1 (Lin neg , CD44 hi , CD25 - ), DN2 (Lin neg , CD44 hi , CD25 + ), DN3 (Lin neg , CD44 low , CD25 + ) and DN4 (Lin neg , CD44 low , CD25 - ) populations by flow cytometry. Numbers within FACS plots indicate cell percentages. Total number of DN1, DN2, DN3 and DN4 cells were measured by flow cytometry. N = 20. Bars indicate means +- stand

Product Specific Information

Description: The D7 monoclonal antibody reacts with mouse Sca-1, an 18 kDa member of the Ly-6 family of GPI-linked surface proteins. D7 reacts with both Ly-6E.1 and Ly-6A.2 molecules expressed by mouse hematopoietic stem cells, myeloid population and peripheral T and B cells. Non-activated splenocytes from Ly-6.2 strains including C57BL, SJL, 129, AKR, and others demonstrate higher frequency of D7-positive cells compared to the Ly-6.1 strains such as BALB/c, C3H, NZB and others. Sca-1 is expressed at high levels upon activation regardless of the Ly-6 haplotype. The Ly-6 family is involved in regulation and function of T cell activation. Sca-1 is a major phenotypic marker for mouse hematopoietic progenitor/stem cell subset.

Applications Reported: This D7 antibody has been reported for use in flow cytometric analysis.

Applications Tested: This D7 antibody has been tested by flow cytometric analysis of mouse splenocytes. This can be used at less than or equal to 0.06 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.

Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Please protect this vial and stained samples from light.

Fixation: Samples can be stored in IC Fixation Buffer (cat. 00-8222) (100 µL of cell sample + 100 µL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (cat. 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically.

Excitation: 488-561 nm; Emission: 775 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser.

Filtration: 0.2 µm post-manufacturing filtered.
