The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 32, 40 kDa (predicted molecular weight: 40 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.


  • Function
    Binds to the 37-bp core of the locus control region (LCR) of the red/green visual pigment gene cluster. May regulate the activity of the LCR and the cone opsin genes at earlier stages of development.
  • Tissue specificity
    In the adult eye, expressed in lens, iris, ciliary body, choroid, optical nerve head and, most strongly, in retina, but not expressed in sclera and cornea. According to PubMed 11978762, expressed in adult retina but not in lens and cornea. Within adult retina, found exclusively in the inner nuclear layer. Isoform 1, isoform 2, isoform 3 and isoform 4 expressed in adult retina, but not in brain, heart, kidney, liver, lung, pancreas, placenta and skeletal muscle. Not expressed in thymus and spleen. Expressed in embryonic craniofacial tissue. Expressed in fetal (week 14) retina. Strongly expressed in neonatal retina (day 0), weakly in neonatal lens (day 0), choroid (day 0) and cornea (day 0, 4; month 9).
  • Involvement in disease
    Defects in VSX1 are a cause of posterior polymorphous corneal dystrophy type 1 (PPCD1) [MIM:122000]. PPCD1 is a slowly progressive hereditary disorder of the corneal endothelium that leads to a variable degree of visual impairment usually in adulthood.
    Defects in VSX1 are a cause of keratoconus type 1 (KTCN1) [MIM:148300]. Keratoconus type 1 is a frequent corneal dystrophy with an incidence that varies from 50 to 230 per 100'000. The cornea assumes a conical shape as a result of a progressive non-inflammatory thinning of the corneal stroma. Keratoconus is most often an isolated sporadic condition with cases of autosomal dominant and autosomal recessive transmission.
