Description: TRITC (Tetramethylrhodamine isothiocyanate) is a popular rhodamine derivative pink in color but emits a red-orange color upon Emission at 580nm. TRITC is frequently paired with FITC in double labeling experiments and conjugated antibodies are often used in immunofluorescence microscopy, flow cytometry, FLISA (fluorescent ELISA) and high throughput screening assays. These conjugates are best excited with the 532 nm spectral line of the He-Ne laser and are also recommended as a second color detection reagent in in situ hybridization applications. (Excitation/Emission = 555nm / 580nm Emission Color = Orange to Red (Similar Dyes: Alexa Fluor 555, Cy3, DyLight 550)

Description: ImmunoReagents’ Biotinylated antibody conjugates are widely used due to their ability to enhance antibody signal in most immunoassays. Biotinylated secondary antibodies are used in most immunoassay formats (i.e., ELISA, Immunohistochemistry (IHC), and Western blotting). While Biotinylated antibodies by themselves do not produce a signal that can be visualized, biotin has a high affinity and specificity to Streptavidin/Avidin. Using ImmunoReagents’ streptavidin conjugates with biotinylated antibodies results in signal amplification.

Description: The Hit3a antibody is specific for human CD3e, also known as CD3 epsilon, a 20 kDa subunit of the T cell receptor complex, along with CD3 gamma and CD3 delta. These integral membrane protein chains assemble with additional chains of the T cell receptor (TCR), as well as CD3 zeta chain, to form the T cell receptor – CD3 complex. Together with co-receptors CD4 or CD8, the complex serves to recognize antigens bound to MHC molecules on antigen-presenting cells. These interactions promote T cell receptor signaling (T cell activation), inducing cell proliferation, differentiation, production of cytokines or activation-induced cell death. CD3 is differentially expressed during thymocyte-to-T cell development and on all mature T cells.

Description: The HI30 antibody reacts with human CD45, one of the most abundant hematopoietic markers and one that is expressed on all leukocytes (the Leukocyte Common Antigen, LCA). CD45 is a protein tyrosine phosphatase existing in several isoforms, each being generated and expressed in cell-specific patterns. With its broad cell distribution, CD45 is critical for many leukocyte functions, regulating signal transduction and cell activation associated with the T cell receptor, B cell receptor, and IL-2 receptor. Other forms of CD45, with restricted cellular expression, include CD45R (B220), CD45RA, CD45RB, CD45RO and others.

Description: The 1A8 antibody binds to mouse Ly-6G, commonly known as Gr-1, a member of the Ly-6 superfamily of GPI-anchored cell surface proteins with roles in cell signaling and cell adhesion. Gr-1 is differentially expressed during development and maturation of cells in the myeloid lineage and is expression at varying stages and levels on monocytes, macrophages, granulocytes, and peripheral neutrophils.

Description: The SK1 antibody is specific for the 32-34 kDa alpha chain of human CD8, known as CD8a or CD8 alpha. CD8a can form a homodimer (CD8 alpha-alpha), but is more commonly expressed as a heterodimer with a second chain known as CD8b or CD8 beta. CD8 acts as a co-receptor for antigen recognition and subsequent T cell activation that is initiated upon binding of the T cell receptor (TCR) to antigen-bearing MHC Class I molecules. The cytoplasmic domains of CD8 provide binding sites for the tyrosine kinase lck, facilitating intracellular signaling events that lead to T cell activation, development, and cytotoxic effector functions. CD8+ cytotoxic T cells (CTLs) play an important role in inducing cell death of tumor cells, as well as cells infected by virus, bacteria or parasites.

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 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.

Description: Accumulation of the amyloid-beta peptide (Abeta) in the cerebral cortex is a critical event in the pathogenesis of Alzheimer's disease. The beta-amyloid protein precursor (APP) is cleaved by one of two beta-secretases (BACE and BACE2), producing a soluble derivative of the protein and a membrane anchored 99-amino acid carboxy-terminal fragment (C99). The C99 fragment serves as substrate for gamma-secretase to generate the 4 kDa amyloid-beta peptide (Abeta), which is deposited in the Alzheimer's disease patient's brains. Recently, Death Receptor 6 (DR6) was found to interact with an amino-terminal fragment of the Beta-amyloid protein (N-APP) in neurons, activating a caspase 6-dependent apoptotic event leading to axonal degeneration and pruning during development, suggesting that these two proteins are involved in neural development and may possibly play a role in Alzheimer's disease.

Description: The amphoterin-induced gene and ORF (AMIGO1) protein is a brain-enriched, glycosylated transmembrane immunoglobulin (Ig) superfamily protein with six extracellular leucine-rich repeats (LRRs) and one Ig-like domain. It and the related proteins AMIGO2 and AMIGO3 are thought to be cell adhesion molecules expressed on fiber tracts of neuronal tissues and participate in their formation (1). AMIGO1 has also been suggested to play important roles in dendritic outgrowth during development and could modulate the survival of developing and adult neurons (2).
