Validation Data Gallery

• 

  IP using His Fab-Trap® Agarose (hfa) from untransfected HEK293T (mock) and HEK293T cells transfected with either His-TOM70 or TOM70-His fusion proteins. WB detection of TOM70 protein was also done on samples from the Input (I), Flow-Through (F), and Bound (B) fractions using Anti-TOM70 Polyclonal Antibody (14528-1-AP) and ChromoTek Nano-Secondary alpaca anti-rabbit IgG, CoraLite Plus 488 (srb2GCL488-1).

• 

  His Fab-Trap® Agarose (hfa) was used for the Co-IP of AurKinB-His fusion protein and interacting partners from untransfected (mock) and transfected HEK293T cells. Multiplexed WB was done on Input (I), Flow-Through (F), and Bound (B) fractions of the IP. Detection was completed using His-tag Monoclonal Antibody (66005-1-Ig) labeled with FlexAble CoraLite Plus 647 Kit for Mouse IgG (KFA023), CDC37 Monoclonal Antibody (66420-1-Ig) labeled with FLexAble CoraLite Plus 750 Kit for Mouse IgG2a (KFA044), and HSP90AB1 Monoclonal Antibody (67450-1-Ig) labeled with FlexAble CoraLite Plus 488 Kit for Mouse IgG2b (KFA061).

• 

  IP of His-TOM70 and TOM70-His proteins using either His Fab-Trap Agarose (left) or a competitor resin product (right) from transfected HEK293T cells. The His Fab-Trap pulls down the TOM70 proteins more efficiently and with less background when compared to the competitor.
