Anti-Human CD4 (OKT4) ColorWheel^?Dye-Ready mAb

半岛bd体育手机客户端 说明

一般描述

ColorWheel^?technologyis a novel and proprietary method of creating your own antibody and dye combinations for use in flow cytometry. By incubating any ColorWheel^?antibody with any ColorWheel^?dye, researchers can quickly and simply produce primary conjugated antibodies for use in single color or multicolor flow cytometry analysis. Each ColorWheel^?antibody and dye is lyophilized for long long-term storage, allowing for simplicity and flexibility without compromise. ColorWheel^?technologyrequires both ColorWheel^?antibody and ColorWheel^?dyefor Flow Cytometry application.

目标描述

T-cell surface glycoprotein CD4 (UniProt: P01730; also known as T-cell surface antigen T4/Leu-3, CD4) is encoded by the CD4 gene (Gene ID: 920) inn human. CD4 is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-25), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 26-396), a transmembrane domain (aa 397-418), and a cytoplasmic domain (aa 419-458). CD4 is highly expressed in T-helper cells and its expression is also observed in macrophages, dendritic cells, and NK cells. It plays an essential role in the immune response and serves multiple functions in responses against both external and internal offenses. In T-cells, it functions primarily as a coreceptor for MHC class II molecule:peptide complex. It is shown to interact simultaneously with the T-cell receptor (TCR) and the MHC class II presented by antigen presenting cells. In turn, it recruits LCK to the vicinity of the TCR-CD3 complex and then LCK initiates different intracellular signaling pathways by phosphorylating various substrates, which ultimately lead to lymphokine production, motility, adhesion, and activation of T-helper cells. The OKT4 antibody binds to the D3 domain of CD4 and can be used as a phenotypic marker for CD4 expression. (Ref.: Helling, B., et al. (2015). Immunol. Cell Biol. 93(4); 396-405; Healey, D., et al. (1990). J. Exp. Med. 172(4); 1233-1242).

外形

Lyophilized from PBS containing D-Mannitol and Sucrose, normal appearance is a dried pellet. Reconstituted antibody solution is stable and functional as assessed by functional testing. Contains no biocide or preservatives, such as azide.

重悬

1.0 mg/mL after reconstitution at 25 μL in PBS. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

储存及稳定性

Recommend storage of lyophilized product at 2-8℃. Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial. Reconstitute each vial by adding 25 μL of PBS. Protect from light.
