The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
- First try to dissolve a small amount of peptide in either water or buffer. The more charged residues on a peptide, the more soluble it is in aqueous solutions. - If the peptide doesn’t dissolve try an organic solvent e.g. DMSO, then dilute using water or buffer. - Consider that any solvent used must be compatible with your assay. If a peptide does not dissolve and you need to recover it, lyophilise to remove the solvent. - Gentle warming and sonication can effectively aid peptide solubilisation. If the solution is cloudy or has gelled the peptide may be in suspension rather than solubilised. - Peptides containing cysteine are easily oxidised, so should be prepared in solution just prior to use.
Preparation and Storage
Stability and Storage
Shipped at 4°C. Store at -20°C or -80°C.
Ceroid-lipofuscinosis, neuronal 8 (epilepsy, progressive with mental retardation)
Could play a role in cell proliferation during neuronal differentiation and in protection against cell death.
Involvement in disease
Defects in CLN8 are the cause of neuronal ceroid lipofuscinosis type 8 (CLN8) [MIM:600143]. A form of neuronal ceroid lipofuscinosis with onset in childhood. Neuronal ceroid lipofuscinoses are progressive neurodegenerative, lysosomal storage diseases characterized by intracellular accumulation of autofluorescent liposomal material, and clinically by seizures, dementia, visual loss, and/or cerebral atrophy. The lipopigment patterns observed most often in neuronal ceroid lipofuscinosis type 8 comprise mixed combinations of granular, curvilinear, and fingerprint profiles. Defects in CLN8 are the cause of neuronal ceroid lipofuscinosis type 8 Northern epilepsy variant (CLN8NE) [MIM:610003]. A form of neuronal ceroid lipofuscinosis clinically characterized by epilepsy that presents between 5 and 10 years of age with frequent tonic-clonic seizures followed by progressive mental retardation. Visual loss is not a prominent feature. Intracellular accumulation of autofluorescent material results in curvilinear and granular profiles on ultrastructural analysis.
