Technical Data
Aquaporin 5 (AQP5)
Water is a critical component of all living cells. Interestingly, tissue membranes show a great degree of water permeability. Mammalian red cells, renal proximal tubules, and descending thin limb of Henle are extraordinarily permeable to water. Water crosses hydrophobic plasma membranes either by simple diffusion or through a facilitative transport mechanism mediated by special protein “aquaporin”. Over the last decade, genes for several members of aquaporin family (AQP1-9 and AQPAP) have been cloned, expressed, and their distribution studied in many tissues. AQP5 (human, mouse, and rat 265aa) is found in several epithelial tissues (salivary and lachrymal glands, corneal epithelium in the eye and lung). It is implicated in generation of saliva, tears, and pulmonary secretions. AQP families of proteins are predicted to contain six transmembrane domains.

Suitable for use in ELISA, Western Blot, Immunohistochemistry and Immunofluorescence. Other applications not tested.

Recommended Dilutions:
ELISA: 0.5-1ug/ml; Coat plates with control peptide at 1ug/ml.
Western Blot: 1-10ug/ml (ECL)
Immunohistochemistry (PFFE): 2-10ug/ml
Immunofluorescence (PFFE): 2-10ug/ml
Note: The use of 0.5-1% milk in all primary/secondary antibody-enzyme conjugate incubations is recommended to suppress non-specific bands.
Optimal dilutions to be determined by the researcher.

Control Peptide: A3000-23: Aquaporin 5 (AQP5), Rat

Storage and Stability:
Lyophilized 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. 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.
