C4.4A (Ly6/PLAUR-domain containing protein 3; also MIG-C4 and GPI-anchored metastasis-associated protein C4.4A) is an 85-95kD, variably glycosylated member of the Ly6 family of GPI-anchored proteins. It is expressed on transitional epithelium, keratinocytes and monocytes, and binds laminin 1 and 5, plus Galectin-3. C4.4A is believed to support cell migration.
Applications
Suitable for use in Western Blot, Immunohistochemistry and ELISA. Other applicatons not tested.
Recommended Dilutions
Western Blot: 1ug/ml. Tissue lysates were resolved by SDS-PAGE, transferred to an Immobilon-P membrane and immunoblotted. Immunohistochemistry: 2-15ug/ml will detect C4.4A in cells and tissues. Optimal dilution determined by the researcher.
Storage and Stability
Lyophilized and reconstituted products are stable for 12 months after receipt at -20°C. Reconstitute with sterile PBS. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
