Extra Details:: MaxLight™ 650 is a new Far-IR stable dye conjugate comparable to Alexa Fluor™647, DyLight™649, Cy5™ and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (655nm); Emission (676nm); Extinction Coefficient 250,000. Claudin-18 is a tight junction protein expressed as lung- and stomach-specific isoforms which are generated by alternative splicing of the claudin-18 gene.1 The lung-specific form is a downstream target gene regulated by the T/EBP/NKX2.1 transcription factor.1 A splice variant lacking the C-terminal cytoplasmic domain also exists in mouse, but has not been confirmed in human.1 Human claudin-18 demonstrates 88% amino acid sequence identity to the mouse protein.1 Immunohistochemical studies have demonstrated complete membrane localization of claudin-18 in lung and stomach epithelial cells, while electron microscopy has shown that it is concentrated in the cell-cell borders of these cells.1 These features suggest a potentially important role for claudin-18 in the structure and function of tight junctions in the lung and stomach.1 Claudin-18 expression has also been reported in the inner ear.2 Applications: Suitable for use in Western Blot, Immunofluorescence, and Immunohistochemistry Other applications not tested. Recommended Dilution: Immunohistochemistry: frozen and paraffin sections Optimal dilutions to be determined by the researcher. Positive Control: Mouse lung and stomach homogenates Storage and Stability: Store product at 4°C in the dark. DO NOT FREEZE! Stable at 4°C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: MaxLight™650 conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Note: Applications are based on unconjugated antibody.
