Biolegend, 317357, Cell-Vive™ GMP Ultra-LEAF™ Biotin anti-human CD3 SF Antibody, 100μg

CD3ε is a 20 kD chain of the CD3/T cell receptor (TCR) complex, which is composed of two CD3ε, one CD3γ, one CD3δ, one CD3ζ (CD247), and a T cell receptor (α/β or γ/δ) heterodimer. It is found on all mature T lymphocytes, NK T cells, and some thymocytes. CD3, also known as T3, is a member of the immunoglobulin superfamily that plays a role in antigen recognition, signal transduction, and T cell activation. GMP Ultra-LEAF™ Biotin anti-human CD3 SF Antibody was GMP manufactured under serum-free conditions including serumfree hybridoma cell culture, without additional animal or humanderived materials or preservatives. This antibody contains ultra-low levels of endotoxin (<0.01EU/μg of protein), is filtered through a 0.1 μm membrane, and is tested negative for mycoplasma and microbial growths. GMP Ultra-LEAF™ Biotin anti-human CD3 SF Antibody is for research and further ex vivo bioprocessing use only. BioLegend Cell-Vive™ GMP Ultra-LEAF™ antibodies are manufactured and tested in accordance with USP Chapter 1043, Ancillary Materials for Cell, Gene and Tissue-Engineered Products and Ph. Eur. Chapter 5.2.12 in a dedicated GMP facility compliant with ISO 13485:2016. Specifications and processes include:
100μg
Reactivity: Human
Antibody Type: Monoclonal
Host Species: Mouse
Formulation: 0.1 μm filtered in phosphate-buffered solution, pH 7.2, containing no preservative. Endotoxin level is < 0.01 EU/μg of the protein (< 0.001 ng/μg of the protein) as determined by the LAL test.
Endotoxin Level: Less than 0.01 EU/μg of the protein (< 0.001 ng/μg of the protein) as determined by the LAL test
Preparation: The Ultra-LEAF™ (Low Endotoxin, Azide-Free) antibody was purified by affinity chromatography.
Concentration: 1.0 mg/mL
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C. This Ultra-LEAF™ solution contains no preservative; handle under aseptic conditions.
Application: FC - Quality tested
Recommended Usage: Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.5 µg per million cells in 100 µL volume. It is recommended that the reagent be titrated for optimal performance for each application.
Application Notes: GMP Ultra-LEAF™ Biotin anti-human CD3 SF Antibody (Endotoxin < 0.01 EU/μg, Azide-Free, 0.1 μm filtered) is recommended for highly sensitive assays. The antibody was GMP manufactured under serum-free conditions including serum-free hybridoma cell culture, without additional animal or human-derived materials or preservatives. This antibody is intended for flow cytometry and for research or further ex vivo bioprocessing use only. The OKT3 monoclonal antibody reacts with an epitope on the epsilon-subunit within the human CD3 complex. Clone OKT3 can block the binding of clones SK7 and UCHT14. The OKT3 antibody is able to induce T cell activation. Additional reported applications (for the relevant formats) include: immunohistochemical staining of acetone-fixed frozen sections and activation of T cells.
Additional Product Notes: For plate coating protocols, Biotin anti-human CD3 antibody (Cat. No. 317357/317358) can be used at 1 μg/mL in PBS in combination with 1 μg/mL of Biotin anti-human CD28 antibody (Cat. No. 302978) to efficiently activate T cells. Plates should be coated for 2 hours in a tissue culture incubator or overnight at 4°C. For soluble antibody activation protocols, we recommend 10 μg/mL of anti-human CD3 (Cat. No. 317357/317358) antibody and 5 μg/mL of anti-human CD28 antibody (Cat. No. 302978).
