Flag tag purification protocol
WebJan 18, 2007 · This protocol describes a method that we developed to adapt the tandem affinity purification (TAP) approach for use in mammalian cells. The protocol involves fusing a protein of interest with... WebAffinity purification: It is not recommended to use HA-tags for proteins deriving from apoptotic cells. The HA-tag can be cleaved by Caspases 3 and 7, which results in loss of immunoreactivity. DDDK (FLAG ®, Sigma) Molecular Weight: 1.01 kDa Size: 8 amino acids (DYKDDDDK). Tag Location: C- or N- terminals, or internal.

WebIMAC is a widely-used method for rapidly purifying polyhistidine affinity-tagged proteins, resulting in 100-fold enrichments in a single purification step. The chelators most commonly used as ligands for IMAC are nitrilotriacetic acid …
Weba) The ALFA-tag is small, well-soluble, hydrophilic, and features balanced charges. The tag, therefore, is predicted to have minimal impact on the physiological function of the protein of interest it is fused to. b) The ALFA-tag sequence is absent from common model organisms. WebJan 18, 2007 · The protocol improves upon previously published TAP approaches by employing FLAG in place of calmodulin binding peptide (CBP) with resulting higher recovery during purification.
