Western blotting is an analytical technique for protein identification. It has various applications in immunology and medicine, including detecting diseases like bovine spongiform encephalopathy, mad cow disease, and human and feline immunodeficiency virus from biological samples.
The technique begins with separating proteins from the sample using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), followed by protein transfer, immunoblotting, and finally, protein detection.

Agarose gel electrophoresis is very useful in separating DNA fragments by size. Running a DNA ladder containing fragments of the known length alongside the sample helps determine the approximate length of the sample DNA fragments. However, additional steps are needed to verify the sequence identity of the sample DNA fragments.
Denatured DNA fragments must be transferred onto a carrier membrane from the gel to make it accessible to a probe - a small ssDNA fragment complementary to the target DNA...

Resumen
Los investigadores de neurociencia descubrieron la manipulación de imágenes en numerosos estudios de la enfermedad de Alzheimer. Esto plantea preocupaciones sobre la validez de la hipótesis de la cascada amiloide, una explicación principal para la condición.
Área de la Ciencia:
- La neurociencia
- Investigación biomédica
- Fisiopatología de la enfermedad de Alzheimer
Sus antecedentes:
- La hipótesis de la cascada amiloide ha sido durante mucho tiempo una teoría dominante en la investigación de la enfermedad de Alzheimer.
- Esta hipótesis postula que la acumulación de placas amiloides es un conductor primario de la neurodegeneración.
