Study Notes
PCR Advantages
- PCR is a highly sensitive method, enabling the detection of pathogens at low infection levels
- This sensitivity is due to the amplification of target DNA from pathogens
Sample Preparation for PCR
- Sample preparation involves the extraction of DNA or RNA
PCR Requirements
- The PCR or amplification reaction requires incubation of samples at multiple temperatures
- This process demands specialized equipment and some level of expertise
ELISA Technique
- A laboratory technique used to detect and quantify specific proteins, antibodies, antigens, or hormones in a sample
- Involves the use of an enzyme-linked antigen or antibody to produce a measurable signal, usually a color change, indicating the presence and amount of the target substance
Applications of ELISA
- Widely used in plant pathology to detect plant pathogens, including viruses, bacteria, and fungi, in plant tissues
- Helps in the early diagnosis and management of plant diseases, ensuring healthy crop production and preventing the spread of infections
