What is the purpose of subretinal injection?
The purpose is to deliver target genes to the retinal pigment epithelium for research and therapeutic applications.
What are viral vectors?
Viral vectors are tools used to deliver genetic material into cells, commonly used in gene therapy.
How is the injection performed?
The injection involves exposing the eye, creating a small hole, and injecting the viral vector into the subretinal space.
What is a subretinal bleb?
A subretinal bleb is a localized area of fluid accumulation in the subretinal space, indicating successful injection.
What techniques are used to confirm gene expression?
Immunofluorescence microscopy is used to visualize the expression of fluorescence markers delivered by the viral vectors.
Is this method replicable?
Yes, the method is designed to be easy and replicable for researchers.
