{"product_id":"biolegend-389004","title":"Biolegend, 389004, Ultra-LEAF™ Purified anti-human CD3ε Recombinant Antibody, 1mg","description":"\u003cp\u003eCD3ε 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.\u003cbr\u003e\n1mg\u003cbr\u003e\nVerified Reactivity: Human\u003cbr\u003e\nAntibody Type: Recombinant\u003cbr\u003e\nHost Species: Human\u003cbr\u003e\nFormulation: 0.2 µm filtered in 150 mM NaCl, pH 6.5, containing no preservative\u003cbr\u003e\nEndotoxin Level: Less than 0.01 EU\/µg of the protein (\u0026lt; 0.001 ng\/µg of the protein) as determined by the LAL test.\u003cbr\u003e\nPreparation: The Ultra-LEAF™ (Low Endotoxin, Azide-Free) antibody was purified by affinity chromatography.\u003cbr\u003e\nConcentration: The antibody is bottled at the concentration indicated on the vial, typically between 2 mg\/mL and 3 mg\/mL.

However, upon request, this can be tested on a custom basis with an outside, independent laboratory.\u003cbr\u003e\nQ: Does BioLegend test each Ultra-LEAF™ antibody by functional assay?\u003cbr\u003e\nA: No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.\u003cbr\u003e\nQ: Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?\u003cbr\u003e\nA: No, BioLegend does not test for pathogens in-house unless otherwise indicated.  However, we can recommend an outside vendor to perform this testing as needed.\u003cbr\u003e\nQ: Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?\u003cbr\u003e\nA: We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.\u003c\/p\u003e","brand":"Biolegend","offers":[{"title":"Default Title","offer_id":46866194432169,"sku":"389004","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/biolegend-389004","provider":"Iright","version":"1.0","type":"link"}
