Precipitation using ammonium sulphate is one of the oldest method and widely applicable approach for partial purification of antibodies. In solution, a large number of water molecules are bound to the sulphate ion reducing the amount of water available to interact with the protein molecules.recipitation using ammonium sulphate is one of the oldest method and widely applicable approach for partial purification of antibodies.

Autism is a spectrum disorder, meaning a person can be a little autistic or very autistic, and individuals can have varying symptoms. The term broad autism phenotype describes an even wider range of individuals who exhibit problems with personality, language, and social-behavioral characteristics at a level that is considered to be higher than average but lower than is diagnosable with autism.
Down syndrome (DS or DNS), also known as trisomy 21, is a genetic disorder caused by the presence of all, or part of a third copy of chromosome 21. It is typically associated with physical growth delays, characteristic facial features, and mild to moderate intellectual disability. The average IQ of a young adult with Down syndrome is 50, equivalent to the mental age of an 8- or 9-year-old child, but this can vary widely.
