This study investigates the relationship between age and neurogenesis-related protein levels in cerebrospinal fluid (CSF). By analyzing CSF samples, the research aims to understand how neurogenesis declines with age.
Begin with cerebrospinal fluid, or CSF, collected from individuals of various ages.
Centrifuge the sample to pellet cellular debris and collect the supernatant.
The supernatant contains proteins involved in neuron generation or neurogenesis.
Take a multiwell plate coated with streptavidin. Add a blocking agent to prevent nonspecific binding.
Add biotin-labeled capture antibodies selective to the specific neurogenesis-related proteins.
Incubate with agitation to bind the antibodies to streptavidin, then wash the plate.
Add the CSF sample along with ruthenium-labeled detection antibodies to the wells, then incubate with agitation.
The specific neurogenesis-related proteins bind to capture antibodies and interact with detection antibodies simultaneously.
Wash the plate thoroughly and add a detection buffer.
Place the plate in an imaging system.
The detection buffer triggers light emission from the ruthenium.
A decrease in light intensity across the samples indicates age-related reductions in neurogenesis-related protein levels, confirming a decline in neurogenesis.
