CD152 (CTLA-4) Antibody (16-1529-82) in Flow
STAR protocols 2024 -
Example of unsupervised analysis of flow cytometry data of CD8+ T cells treated with AML EVs, using CRUSTY platform For this analysis, two samples (CTRL and AML EVs), 3.000 cells each, were clustered using FlowSOM algorithm, based on expression of 6 markers of T cells exhaustion (TIM-3, LAG-3, PD-1, TIGIT, CTLA-4, CD39). Cells were pre-gated in FlowJo as viable CD8+ cells (as in Figure 7 A) and downsampled ... View More

产品详细信息
Description: The 14D3 monoclonal antibody reacts with human CD152, also known as cytotoxic T lymphocyte antigen-4 (CTLA-4). CTLA-4, a protein with structural similarities to CD28, is expressed on activated T cells (activated B cells may also express CTLA-4) and binds the B7 family members, CD80 (B7-1) and CD86 (B7-2), with higher affinity than CD28 does. CTLA-4 and CD28 appear to deliver opposing signals to T cells: while CD28 is a potent costimulator, CTLA-4 restricts the progression of T cells to an activated state by inhibiting IL-2 secretion and cellular proliferation. The cytoplasmic portion of CTLA-4 contains ER retention motifs, resulting in intracellular localization of a large proportion of newly synthesized CTLA-4 in response to TCR signaling.
The 14D3 antibody also recognizes rhesus monkey and has inhibitor activity.
Applications Reported: The 14D3 antibody has been reported for use in flow cytometric analysis. It has also been reported in in vitro inhibition studies. (Please use Functional Grade purified 14D3 in functional assays).
Applications Tested: The 14D3 antibody has been tested by flow cytometric analysis of PHA stimulated normal human peripheral blood cells. This can be used at less than or equal to 0.25 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.
Furthermore, due to the intracellular localization of a large portion of CTLA-4, for complete detection it may be necessary to assess intracellular expression, in addition to surface expression of CTLA-4.
Storage and handling: Use in a sterile environment.
Filtration: 0.2 µm post-manufacturing filtered.
Purity: Greater than 90%, as determined by SDS-PAGE.
Endotoxin Level: Less than 0.001 ng/µg antibody, as determined by LAL assay.
Aggregation: Less than 10%, as determined by HPLC.
靶标信息
CTLA4 (Cytotoxic T-Lymphocyte Antigen 4) is a CD28-family receptor expressed on mainly CD4+ T cells. It binds the same ligands as CD28 (CD80 and CD86 on B cells and dendritic cells), but with higher affinity than CD28. However, in contrast to CD28 which enhances cell function when bound at the same time as the T cell receptor, CTLA4 inhbits the T cell and prevents it from functioning. Intracellular CTLA4 is also found in regulatory T cells and may be important to their function.
