          Product Specific Information

          Notice: The eVolve™ line of antibody conjugates will be discontinued at the end of February, 2018 and replaced with our improved Invitrogen™ eBioscience™ Super Bright conjugated antibodies for flow cytometry. Individual eVovle catalog numbers will become unavailable as inventory depletes. This item has a corresponding Super Bright 600 format available - please see Product # 63-0458-42. We will continue to offer a selection of Qdot conjugated antibodies.

          Description: The HI100 monoclonal antibody reacts with human CD45RA, a 220 kDa molecule expressed by subpopulations of CD4+ peripheral T lymphocytes, CD8+ peripheral T lymphocytes, and B cells. The CD45RA+ T cell populations are mainly naive/virgin allowing the use of HI100 mAb as a phenotypic marker to discriminate T cell subsets.

          Applications Reported: This HI100 antibody has been reported for use in flow cytometric analysis.

          Applications Tested: This HI100 antibody has been pre-titrated and tested by flow cytometric analysis on normal human peripheral blood cells. This can be used at 5 µL per test. A test is defined as the amount 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.

          For best results when using antibodies conjugated to eVolve™, we recommend a quick spin of the vial before use and avoid touching the bottom of the vial with the pipet tip.

          Laser/Filter Recommendation: eVolve™ 605 can be optimally excited with laser lines from 325-405 nm, and emits near 610 nm. We recommend using the violet (405 nm) laser line for excitation and a 595LP with a 605/40 or 610/20 bandpass filter, or equivalent, for detection.

          Fixation Recommendation: Antibodies conjugated to eVolve™ are compatible with eBioscience's fixation and permeabilization buffers.

          Excitation: 350-590 nm; Emission: 605 nm; Laser: Ultraviolet Laser, Violet Laser

          Storage and handling: For best results when using antibodies conjugated to eVolve™, we recommend a quick spin of the vial before use and avoid touching the bottom of the vial with the pipet tip.

          Target Information

          CD45RA is an isoform of the CD45 complex and has restricted expression between different subtypes of lymphoid cells. CD45 (LCA, leukocyte common antigen) is a receptor-type protein tyrosine phosphatase ubiquitously expressed in all nucleated hematopoietic cells, comprising approximately 10% of all surface proteins in lymphocytes. CD45 glycoprotein is crucial in lymphocyte development and antigen signaling, serving as an important regulator of Src-family kinases. CD45 protein exists as multiple isoforms as a result of alternative splicing and these isoforms differ in their extracellular domains, however, they share identical transmembrane and cytoplasmic domains. CD45 isoforms differ in their ability to translocate into the glycosphingolipid-enriched membrane domains and their expression depends on cell type and physiological state of the cell. Besides the role in immunoreceptor signaling, CD45 is important in promoting cell survival by modulating integrin-mediated signal transduction pathway and is also involved in DNA fragmentation during apoptosis. CD45 is expressed on cells of the human hematopoietic lineage, with the exception of mature red cells and is not detected on differentiated cells of other tissues. It is likely that CD45 plays an important role in signal transduction, inhibition or upregulation of various immunological functions. Diseases associated with CD45 dysfunction include severe combined immunodeficiency and Hepatitis C.
