CD4 Antibody (64-5040-42) in Flow

Normal canine peripheral blood cells were stained with CD5 Monoclonal Antibody, PE (Product # 12-5050-42) and 0.06 µg of Rat IgG2a kappa Isotype Control, Super Bright 645 (Product # 64-4321-82) (left) or 0.06 µg of CD4 Monoclonal Antibody, Super Bright 645 (right). Cells in the lymphocyte gate were used for analysis.

产品详细信息

Description: The YKIX302.9 monoclonal antibody reacts with canine CD4, a cell surface receptor expressed on a majority of thymocytes, a subpopulation of mature T cells and dendritic cells. In dogs, CD4 is also highly expressed on neutrophils. CD4 binds to MHC class II on the surface of antigen presenting cells and plays an important role in T cell development and homeostasis.

This YKIX302.9 monoclonal antibody has been reported to block MHC II-restricted T cell responses in vivo and in vitro.

Applications Reported: This YKIX302.9 antibody has been reported for use in flow cytometric analysis.

Applications Tested: This YKIX302.9 antibody has been pre-titrated and tested by flow cytometric analysis of normal canine peripheral blood cells. This can be used at 5 µL (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.

Super Bright 645 is a tandem dye that can be excited with the violet laser line (405 nm) and emits at 645 nm. We recommend using a 660/20 bandpass filter. Please make sure that your instrument is capable of detecting this fluorochrome.

When using two or more Super Bright dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Complete Staining Buffer (Product # SB-4401) to minimize any non-specific polymer interactions. Please refer to the datasheet for Super Bright Staining Buffer for more information.

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 (Product # 00-8222) (100 µL of cell sample + 100 µL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 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: 405 nm; Emission: 645 nm; Laser: Violet Laser

靶标信息

The CD4 antigen is involved in the recognition of MHC class II molecules and is a co-receptor for HIV. CD4 is primarily expressed in a subset of T-lymphocytes, also referred to as T helper cells, but may also be expressed by other cells in the immune system, such as monocytes, macrophages, and dendritic cells. At the tissue level, CD4 expression may be detected in thymus, lymph nodes, tonsils, and spleen, and also in specific regions of the brain, gut, and other non-lymphoid tissues. CD4 functions to initiate or augment the early phase of T-cell activation through its association with the T-cell receptor complex and protein tyrosine kinase, Lck. It may also function as an important mediator of direct neuronal damage in infectious and immune-mediated diseases of the central nervous system. Multiple alternatively spliced transcripts have been identified in this gene [RefSeq, July 2017].
