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 Western Blot, Immunohistochemistry and ELISA. Other applicatons not tested.
Recommended Dilution:
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.
Direct ELISA: 0.5-1ug/ml. The detection limit is ~0.3ng/well.
Optimal dilutions should be determined by each laboratory for each application.
Storage and Stability:
Lyophilized powder may be stored at -20 degrees C. Stable for 12 months at -20 degrees C. Reconstitute with sterile PBS. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Reconstituted product is stable for 12 months at -20 degrees 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.
