Anti-Human CD44 (IM7) ColorWheel® Dye-Ready mAb CWA-1002-25UL

Specificity
Clone IM7 is a rat monoclonal antibody that detects CD44.
Dexamethasone-induced murine myeloid leukemia M1 cells.
Quality Control Testing:
Evaluated by Flow Cytometry in mouse splenoctytes.
Flow Cytometry Analysis (FC): Staining of one million mouse splenocytes was performed using 5 µL of 1:1 mixture of Cat. No. CWA-1002, Anti-Human CD44 (IM7) Colorwheel® Dye-Ready mAb and and Cat. No. CWD-PE Colorwheel® Antibody-Ready Phycoerythrin (PE) Dye or an equivalent amount of PE-conjugated Rat IgG2b isotype control.
Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user
Anti-Human CD44 (IM7) ColorWheel<® technology is a novel and proprietary method of creating your own antibody and dye combinations for use in flow cytometry. By incubating any Colorwheel® antibody with any Colorwheel® dye, researchers can quickly and simply produce primary conjugated antibodies for use in single color or multicolor flow cytometry analysis. Each Colorwheel® antibody and dye is lyophilized for long long-term storage, allowing for simplicity and flexibility without compromise
Target description
CD44 antigen (UniProt: P15379; also known as CDw44, Epican, Extracellular matrix receptor III, ECMR-III, GP90 lymphocyte homing/adhesion receptor, HUTCH-I, Heparan sulfate proteoglycan, Hermes antigen, Hyaluronate receptor, Phagocytic glycoprotein 1, PGP-1, Phagocytic glycoprotein I, PGP-I, CD44) is encoded by the CD44 (also known as LHR, MDU2, MDU3, MIC4) gene (Gene ID: 12505) in murine species. CD44 is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-22), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 23-685), a transmembrane domain (aa 686-707), and a cytoplasmic domain (aa 707-778). It is expressed on all leukocytes, endothelial cells, hepatocytes, and mesenchymal cells. The main ligand for CD44 is Hyaluronic acid (HA) that is expressed by stromal and cancer cells. HA binds the CD44 ligand binding domain and induces conformational changes that allow binding of adaptor proteins or cytoskeletal elements to intracellular domains. This leads to the activation of various signaling pathways leading to cell proliferation, adhesion, migration, and invasion. Overexpression of CD44 has been reported in several cell types and it is considered as an ideal marker for cancer stem cells. (Ref.: Chen, C., et al. (2018). J. Hematol. Oncol. 11; Article 64).
Physical form
Lyophilized from PBS containing D-Mannitol and Sucrose, normal appearance is a dried pellet. Reconstituted antibody solution is stable and functional as assessed by functional testing. Contains no biocide or preservatives, such as azide.
Reconstitution
1.0 mg/mL after reconstitution at 25 μL in PBS. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.
Storage and Stability
Recommend storage of lyophilized product at 2-8°C. Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial. Reconstitute each vial by adding 25 μL of PBS. Protect from light.
