  • Image of Purified Anti-Human CD28 (CD28.2)

    Tonbo Biosciences
    Item #:
    C838Y62

    The CD28.2 antibody reacts with human CD28, a 44 kDa type I surface glycoprotein which acts as a co-stimulatory receptor in support of the T cell receptor (TCR). CD28 exists as a homodimer with specificity for two known ligands, known as B7-1 (CD80) and B7-2 (CD86), which are expressed on activated...

  • Image of Purified Anti-Mouse CD16 / CD32 (2.4G2)

    Tonbo Biosciences
    Item #:
    C838Y63

    The 2.4G2 antibody is specific for a common epitope found in the extracellular regions of mouse Fc-receptors Fc-gamma II (CD32) and Fc-gamma III (CD16). As these are receptors for the Fc portion of mouse IgG, they may also bind laboratory antibody preparations and products used in a variety of cell...

  • Image of PE Anti-Human CD3 (UCHT1)

    Tonbo Biosciences

    The UCHT1 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...

  • Image of violetFluor™ 450 Anti-Human CD8a (RPA-T8)

    Tonbo Biosciences
    Item #:
    C838Y65

    The RPA-T8 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...

  • Image of APC-Cyanine7 Anti-Human/Mouse CD11b (M1/70)

    Tonbo Biosciences
    Item #:
    C838Y66

    The M1/70 antibody reacts with human and mouse CD11b, also known as integrin alpha M. This 165-170 kDa cell surface glycoprotein is part of a family of integrin receptors that mediate adhesion between cells (cell-cell) and components of the extracellular matrix, e.g. fibrinogen (cell-matrix). In...

  • Image of PE Anti-Human IL-17A

    Tonbo Biosciences
    Item #:
    C838Y67
  • Image of Foxp3 / Transcription Factor Staining Buffer Kit

    Tonbo Biosciences
    Item #:
    C838Y68

    Tonbo Biosciences Foxp3 / Transcription Factor Staining Buffer Kit contains specially formulated buffers and solutions for optimal resolution and low background in your analysis of nuclear antigens by flow cytometry. This complete kit contains the following components for use in these staining...

  • Image of PE Anti-Human CD4 (OKT4)

    Tonbo Biosciences
    Item #:
    C838Y69

    The OKT4 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...

  • Image of CFSE

    Tonbo Biosciences
    Item #:
    C838Y70

    CFSE is a non-fluorescent molecule that easily diffuses across cell membranes. Inside the cell, acetate groups are cleaved by intracellular esterases yielding a fluorescent molecule whose succinimidyl ester group covalently interacts with primary amines of intracellular proteins. CFSE is compatible...

  • Image of FITC Anti-Human CD4 (OKT4)

    Tonbo Biosciences
    Item #:
    C838Y71

    The OKT4 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...

  • Image of In Vivo Ready™ Anti-Human CD3 (OKT3)

    Tonbo Biosciences
    Item #:
    C838Y72

    The OKT3 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...

  • Image of Recombinant Human IL-7 (Carrier-free)

    Tonbo Biosciences
    Item #:
    C838Y74

    IL-7 is a hemopoietin family member that factor is produced by bone marrow, thymic stromal cells and spleen cells, among others. This cytokine is a growth factor for progenitor B cells and T cells that signals through the IL-7R, comprised of IL-7Ralpha (CD127) and the common gamma chain (CD132)....
