Description: The GK1.5 antibody reacts with mouse CD4, a 55 kDa protein which acts as a co-receptor for the T cell receptor (TCR) in its interaction with MHC Class II molecules on antigen-presenting cells. The extracellular domain of CD4 binds to the beta-2 domain of MHC Class II, while its cytoplasmic tail provides a binding site for the tyrosine kinase lck, facilitating the signaling cascade that initiates T cell activation. CD4 is typically expressed on thymocytes, certain mature T cell populations such as Th17 and T regulatory (Treg) cells, as well as on dendritic cells. The GK1.5 antibody is widely used as a phenotypic marker for CD4 expression. If used together, the GK1.5 antibody and an alternative antibody, Anti-Mouse CD4 clone RM4-5, will "compete" for binding, i.e. RM4-5 is able to block GK1.5 binding to cells. In contrast, the Anti-Mouse CD4 clone RM4-4 does not block binding of the GK1.5 antibody to cells (Arora S et al. 2006. Infect. Immun. 74: 4339-4348). The GK1.5 antibody is also reported to be cross-reactive with Syrian hamster CD4.

Description: The 2H7 antibody reacts with human CD20, expressed by pre-B cells, resting and activated B cells, follicular dendritic cells and a small subset of T cells, but not on plasma cells. CD20 is a 33-37 kDa transmembrane protein which is differentially phosphorylated in resting and active B cells. The CD20 molecule plays a role in regulating B-cell activation.

Description: The SK3 antibody reacts with human CD4, a 59 kDa protein which acts as a co-receptor for the T cell receptor (TCR) in its interaction with MHC Class II molecules on antigen-presenting cells. The extracellular domain of CD4 binds to the beta-2 domain of MHC Class II, while its cytoplasmic tail provides a binding site for the tyrosine kinase lck, facilitating the signaling cascade that initiates T cell activation. CD4, and co-receptors CCR5 and CXCR4, may also be utilized by HIV-1 to enter T cells. Human CD4 is typically expressed on thymocytes, some mature T cell populations such as Th17 and T regulatory (Treg) cells, as well as on dendritic cells. The SK3 antibody is widely used as a phenotypic marker for human CD4 expression, and has been reported to be cross-reactive with Rhesus and Cynomolgus CD4. This antibody does not block binding of alternative clone RPA-T4, suggesting that they recognize different epitopes.

Description: The 61D3 antibody is specific for human CD14, a 53-55 kDa GPI-anchored glycoprotein. CD14 is highly expressed on monocytes and to a lesser extent on interfollicular macrophages, and some dendritic cells. Together with LPS-Binding Protein (LBP), CD14 binds to and mediates the innate immune response to bacterial lipopolysaccharide (LPS).

Description: The MOPC-21 immunoglobulin is useful as an isotype-matched control. The MOPC-21 immunolglobulin has an unknown binding specificity and is used as an isotype control for mouse IgG1 antibodies.

Description: The fragmentation of genomic DNA by cellular nucleases during the later stages of apoptosis is also one of the most easily measured features of apoptotic cells. Nuclease activity generates DNA fragments ranging from ~300 bp to 50 bp in length, resulting in a typical DNA ‘laddering’ appearance when analyzed by agarose gel electrophoresis. These fragments have exposed 3’-hydroxyl (OH) ends which can be labeled with bromolated deoxyuridine triphosphates (Br-dUTP). An enzyme, terminal deoxynucleotidyl transferase (TdT), is used to catalyze the template-independent addition of Br-dUTP to the 3’-OH ends of double or single stranded DNA. This method is often called TUNEL (terminal deoxynucleotidyl transferase dUTP nick end labeling) or end labeling. Sites where the Br-dUTP is incorporated can then be detected with an antibody specific to BrdU. With the APO-BrdUTM Kit cells are first labeled with Br-dUTP, and then sites of incorporation are detected through staining with a FITC anti-BrdU antibody. Samples can then be analyzed via flow cytometry. Samples that are apoptotic will stain brightly with the anti-BrdU antibody due to the substantial number of exposed 3’-OH sites, while cells that are non-apoptotic will not have incorporated significant amounts of Br-dUTP and will stain dimly. The APO-BrdU Kit is shipped in one container and consists of two packages. Upon arrival one should be stored at 2-8°C and the other at -20°C.
