Used for proteins. The detergent SDS unfolds the proteins and gives them a uniform negative charge, ensuring they are separated strictly by length rather than shape.
It is used to detect abnormal proteins in blood or urine, which can indicate conditions like multiple myeloma or hemoglobin disorders (e.g., sickle cell anemia).
DNA profiling (DNA fingerprinting) uses electrophoresis to compare crime scene samples with suspect DNA. Electrophoresis
Researchers use it to isolate specific genes for cloning or to study mutations. Conclusion
An electrical current is applied. Since DNA and RNA are negatively charged due to their phosphate backbone, they migrate toward the positive electrode (anode). Used for proteins
Electrophoresis is the backbone of several critical scientific fields:
The standard method for separating DNA fragments, often used after a PCR (Polymerase Chain Reaction) to verify results. Since DNA and RNA are negatively charged due
Molecules are loaded into a porous gel, typically made of agarose (for large DNA fragments) or polyacrylamide (for smaller DNA or proteins). This gel acts as a molecular sieve.
