- Applications
Western Blot (Cell lysate)
Western blot using CHK1 polyclonal antibody (Cat # PAB11360) shows detection of bands corresponding to CHK1 in Saccharomyces cerevisiae lysates.
Two strains of S.cerevisiae were tested. Lane 1 shows a predominant band at ~60 KDa. Lane 2 shows a predominant band at ~38 KDa.
Specific band staining is blocked when antibody is preincubated for 45 min at room temperature with 50 ug of peptide immunogen (lanes 3 and 4 respectively).
Lysates were separated by 4-20% SDS-PAGE and transferred onto nitrocellulose.
After blocking, the membrane was probed for 2 h at room temperature with the primary antibody diluted to 1:750 in blocking buffer diluted 1:5 in PBS.
The membrane was washed and reacted with a 1:10,000 dilution of IRDye™800 conjugated Gt-a-Rabbit IgG [H&L] MX for 45 minat room temperature (800 nm channel, green).
Molecular weight estimation was made by comparison to prestained MW markers in lane M (700 nm channel, red).
IRDye™800 fluorescence image was captured using the Odyssey® Infrared Imaging System developed by LI-COR. IRDye is a trademark of LI-COR, Inc.Immunoprecipitation
