Microarrays are quite commonly used and are usually consistent with data obtained from northern blots; however, at times northern blotting is able to detect small changes in gene expression that microarrays cannot.
As micromatrices son bastante usadas e xeralmente son concordantes cos datos obtidos por northern blots; porén, ás veces o northern blot pode detectar pequenos cambios na expresión xénica que pasan desapercibidos nas micromatrices.
