WebSep 30, 2024 · Updated. Hybrid selection is a method that enables selection of specific sequences from a pool of genomic DNA for targeted sequencing analyses via pull-down assays. Typical applications include the selection of exome sequences or pathogen-specific sequences in complex biological samples. Hybrid selection involve the use baits to select … Web(C) STAT1 DNA-binding activity was determined using a pull-down assay with a STAT1 probe. (D) The mRNA expression levels of STAT1 downstream genes, IRF1, TAP1, GBP2, ICAM1, and CXCL10, were measured by qRT-PCR. (E) Correlation of STAT1/STAT3 with colony formation.
WebPull-down Assays. Immunoprecipitation (IP) is a method for selectively isolating a particular protein species from a complex protein solution. The technique relies on antigen/antibody recognition (immuno) and the subsequent mass- or affinity-related isolation of the capture/target complex (precipitation). It is the precipitation of the target ... WebProtein-DNA binding may be analyzed by a number of assays including DNase protection assay, electrophoretic mobility shift assay (EMSA), molecular beacon assay, chromatin immunoprecipitation (ChIP) assay, and a recently described streptavidin-agarose pull-down assay (SAPA) (2-8). The SAPA assay will be described in detail in this chapter.

WebRNA pull-down assays selectively extract a protein–RNA complex from a sample. Typically, the RNA pull-down assay takes advantage of high affinity tags, such as biotin or azido-phosphine chemistry. RNA probes can be biotinylated, complexed with a protein from a cell lysate, and then purified using agarose or magnetic beads.
