Z39Ig Antibody (6H8) is a mouse monoclonal IgG1 kappa light chain antibody that detects Z39Ig protein of human origin by western blotting (WB), immunofluorescence (IF), and flow cytometry (FCM). Anti-Z39Ig antibody (6H8) is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. Z39Ig is a member of the immunoglobulin superfamily of cell adhesion molecules (CAMs), which play a crucial role in mediating cell-cell and cell-matrix interactions. These interactions are vital for numerous biological processes, including cell growth, differentiation, and immune response, as well as in cancer metastasis. Z39Ig is primarily expressed in fetal human tissues, adult lungs, and placenta, highlighting its importance in developmental processes and tissue homeostasis. Z39Ig is localized in the pericentromeric region of human chromosome X, and Z39Ig expression is essential for proper embryonic morphogenic development and neuronal synaptic adhesion, which are critical for learning and memory. Dysregulation or mutation of CAM genes, including Z39Ig, has been implicated in various cancers, affecting tumor growth and metastasis, making Z39Ig a significant target for research in cancer biology and therapeutic interventions.

Can Z39Ig (6H8): sc-53977 monoclonal antibody be used in IF or IHC with mouse tissue or cells? Will there be non-specific staining?

Asked by: TinTin
Thank you for your inquiry. The use of mouse monoclonal antibodies with mouse samples is very common and typically poses no problem. To eliminate any potential cross-reactivity of an anti-mouse secondary detection reagent, Z39Ig (6H8): sc-53977 is available in a variety of direct conjugations, such as HRP, PE, FITC and AlexaFluors.
