How can I be sure if a TF predicted Consensus motif is real or only a frequent repeated sequence?

I used MEME program to analyze the consensus motif of the transcription factor binding site for a Chip Seq analysis. I did a search of this sequence (15 nucleotides) and I found that it is one of the most frequent n-mers in the human genome. What does it means exactly? How can I be sure if my consensus motif is real or only a repetition?

Hi, I am looking for a database/website where I can find the targets of antisense RNAs

I have a list of antisense RNAs and I would like to find their corresponding gene targets. I know you can find one by one, for example in ensembl website, but it is tedious and slow. Does anyone...

Is there a way to modify a protein kinase assay by not drying the acrylamide gel?

I was used to follow the basic protocol for protein kinase assays incubating the sample with radioactive ATP and the purified kinase protein. Later I run the samples in an acrylamide gene and I...

Consensus motif using MEME program. Is it real or is it only a statistically significant repetition?

I did a Chip Seq analysis and I used a MEME program to analyze the consensus motif for the transcription factor binding site. I obtained a long sequence (24 nucleotides). I did a search of this...

What is the minimum number of reads needed to start the data analysis in a Chip-Seq assay?

I obtain around 10 million reads for each sample in my Chip-Seq assay . But after the Bioinformatics clean the sample, map and remove the duplicates we only have around 10% of the reads that we...

Bioinformatic analysis of Chip-seq assay: do I need an Input sample to analyze the seq data? If so, how do I use it?

I did a triplicate of Chip assays, and I sent to sequence these 3 samples and one Input because I read I'll need it for the future bioinformatic analysis of the data. I don't have two different...

Does anyone know HRM channel in a 2 plex QIAGEN Rotor- Gene Q qPCR can be used as a separate channel?

I am going to have 3 different probes in my qPCR work that I am going to do. But I realized that the machine we have in the lab is a Rotor-Gene Q 2plex HRM Platform, saying it has green, yellow,...

Is it possible for two human neuronal cell lines to have different gene sequence for the same protein?

I am looking at the ATP1A2 (Sodium/Potassium ATPase alpha subunit 2) in two human neuronal cell lines. Expression levels of this protein seems to be almost equal when detected by one antibody....

Runs of nucleotides in Sanger sequencing?

I performed site directed mutagenesis, transformation, and then I sent out plasmids for Sanger sequencing and found out that there is extension of DNA just before the stop codon. I am not sure...

I can detect my protein but the encoding DNA sequence has stop codons within. Should I ignore the stop codons?

I constructed a synthetic DNA library (scFv, VH-VL orientation) with a 3' reporter and 8x histag. I cloned and expressed this gene following which I performed an ELISA. The ELISA results suggested...
