CTCF Antibody

This affinity purified antibody was prepared by repeated immunizations with a synthetic peptide corresponding to a region near the C-terminus of CTCF protein.

This product was affinity purified from monospecific antiserum by immunoaffinity chromatography. This antibody reacts with endogenous CTCF protein. A BLAST analysis was used to suggest reactivity with CTCF from human, mouse, horse, bovine, panda, rabbit, Danio, and chicken based on a 100% homology with the immunizing sequence. Cross-reactivity with CTCF from other sources has not been determined.

Store vial at -20° C or below prior to opening. This vial contains a relatively low volume of reagent (25 μL) . To minimize loss of volume dilute 1:10 by adding 225 μL of the buffer stated above directly to the vial. Recap, mix thoroughly and briefly centrifuge to collect the volume at the bottom of the vial. Use this intermediate dilution when calculating final dilutions as recommended below. Store the vial at -20°C or below after dilution. Avoid cycles of freezing and thawing.

CTCF antibody has been tested by ELISA, Immunohistochemistry, and western blotting. Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 82.8 kDa or 150 kDa in size corresponding to CTCF by western blotting in the appropriate cell lysate or extract.
