Less sensitive than ELISA: Western blotting is less sensitive than ELISA, making it more difficult to detect low-abundance proteins. Ideal for identifying specific proteins: Western blots can be used to specifically identify the presence of a target protein in a sample, even when it is present at low levels or in a complex mixture. Longer process with more steps involved: Western blotting is a multi-step process that can take several hours (often overnight) to perform Using the Azure 400 allows you to simultaneously detect 3 target proteins image using three-color fluorescence. Multiplexing using fluorescence allows for the detection of multiple targets in one experiment.

High-throughput: Due to being performed in a 96-well plate, more samples can be processed faster and with less sample needed. Since they are usually performed in 96-well plates, ELISAs allow for many conditions and repeat samples to be tested at once. Versatile: ELISA can be used for both qualitative and quantitative protein analysis on a wide variety of sample types, including serum, cell culture supernatants, and urine. Rapid and easy to perform: ELISA can be performed relatively quickly and requires minimal sample preparation, making it a convenient choice for routine assays. High background: ELISAs can have high background due to cross reactivity of primary and secondary antibodies. Quantitative analysis: ELISA can be used to measure the exact amount of target protein in a sample, making it a valuable tool for determining protein concentration or monitoring changes in protein levels over time.

Limited multiplexing capability: Traditionally, only one protein can be targeted in each ELISA. This makes it an ideal choice for detecting rare or low-abundance proteins. High sensitivity: One of the major advantages of ELISA is its high sensitivity, making it capable of detecting very small amounts of target proteins, even in complex mixtures.
