Format:: Supplied as a liquid in PBS, pH 7.2. Labeled with Allophycocyanin (APC).
Weitere Details:: The full range of color discrimination in humans is based on the presence and function of three cone photoreceptor mechanisms. Each cone type possesses a photo-sensitive pigment-protein complex consisting of 11-cis retinal and a unique opsin protein, which gives sensitivity in the short (S cone, peak sensitivity about 420nm), middle (M cone, peak sensitivity about 530nm with polymorphism; Winderckx et al., 1993; Neitz & Neitz, 1998), and long (L cone, peak sensitivity about 560nm with polymorphism; Neitz & Jacobs, 1990) wavelengths of the light spectrum. All three opsins are transmembrane proteins with seven membrane-spanning regions. Genes for the three types of cone opsins and the rod photoreceptor rhodopsin gene seem to be homologous with varying amounts of conservation. Strongest conservation is between the middle (green) and long (red) wavelength sensitive pigments on the X chromosome, suggesting a relatively recent duplication/divergence event (Nathans, 1989; Nathans et al., 1992). The S cone (blue) opsin is located on chromosome 7 and seems to have stronger conservation with rhodopsin. Cone photoreceptor distribution in humans is dominated by the M and L cone pigments. Applications: Suitable for use in Immunohistochemistry. Other applications not tested. Recommended Dilutions: Immunohistochemistry: Staining with citrate buffer, pH 6.0 is required. Optimal dilutions to be determined by the researcher. 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: APC 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.
