Overview

Aladdin's Biotin-labeled EMSA Probe - C/EBP is a C/EBP consensus oligonucleotide designed for EMSA . This double-stranded oligonucleotide contains the well-recognized binding sequence for the CCAAT/enhancer binding protein (C/EBP), and can be used as a probe for EMSA. The nucleotide sequence of C/EBP consensus oligo is as follows

Precautions：

Avoid heating above 40℃, as double-stranded DNA probe will be denatured at high temperatures into single strands that cannot be used in EMSA.This product is for R&D only. Not for drug, household, or other uses.For your safety and health, please wear a lab coat and disposable gloves during the operation.

If the EMSA bands of target proteins are weak, the dosage of biotin-labeled EMSA probe can be increased to 0.75 µl or 1 µl as appropriate. Note 2: For cold probe competition, the recommended amount of unlabeled probe is 50-100 times that of biotin-labeled probe, but can be adjusted as required.b.Before adding the labeled probe, the reaction mix should be mixed well and incubated at room temperature (20-25℃) for 10 minutes to eliminate possible non-specific binding between probes and proteins. Otherwise allow cold probes react preferentially. Then add the labeled probe, mix well and incubate at room temperature (20-25℃) for 20 minutes.c.Add 1μl of EMSA/Gel-Shift Loading Buffer (colorless, 10X) into each reaction and load onto gel immediately after mixing. Note: Sometimes bromophenol blue can affect protein-DNA interactions. It is recommended to use the colorless EMSA/Gel-Shift Loading Buffer, or that including a very small amount of blue loading buffer to make observation easier.2.For more detailed EMSA procedures with the biotin-labeled probes, please refer to the manual of ’s Chemiluminescent EMSA Kit .
