Clone Host Grade Applications
Monoclonal Mouse Affinity Purified E B IC FC
CD104 (also GP150 and Integrin beta 4) is a 150-200kD member of the integrin beta family. It forms noncovalent heterodimers with integrin alpha 6 and participates in the formation of epithelial hemidesmosomes. Human integrin beta 4 is a type I transmembrane glycoptotein that is 1795 amino acids (aa) in length. It contains a 683aa extracellular domain (ECD) (aa28-710) and a large 1089aa cytoplasmic region. Two ECD alternate splice forms may exist. One shows an 84aa substitution for the 84aa between aa21-704. A second shows a 144aa substitution for the first 704aa. Human beta 4 ECD shares 88% aa sequence identity with mouse beta4 ECD.
Catalog #C2446-01H
ApplicationsSuitable for use in Western Blot, Flow Cytometry, Immunocytochemistry and ELISA. Other applications not tested.
Recommended DilutionsWestern Blot: 1-2ug/ml; Using a colorimetric detection system, the detection limit for recombinant human Integrin 4 is ~25ng/lane under non-reducing conditions. Reducing conditions are not recommended. Chemiluminescent detection will increase sensitivity by 5-50 fold.
Flow Cytometry: 0.2mg/ml; 10ul labels 1-2.5x10e5 human A431 cells in a total reaction volume <200ul.
Immunocytochemistry: 10ug/ml detects CD104 in A431 human epidermoid carcinoma cells. Cells were fixed with PBS, 4% paraformaldehyde for 20 minutes at RT and blocked with PBS, 10% normal donkey serum, 0.1% Triton X-100, 1% BSA for 45 minutes at RT. After blocking, cells were incubated with diluted C2446-01H overnight at 4ºC followed by anti-mouse IgG (FITC) at RT in the dark for 1 hour. Cells were washed with PBS, 0.1% BSA between each step.
Optimal dilutions to be determined by the researcher.
Storage and StabilityLyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile PBS. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Reconstituted product is stable for 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
