The following Col28a1 gene cDNA ORF clone sequences were retrieved from the NCBI Reference Sequence Database (RefSeq). These sequences represent the protein coding region of the Col28a1 cDNA ORF which is encoded by the open reading frame (ORF) sequence. ORF sequences can be delivered in our standard vector, pcDNA3.1+/C-(K)DYK or the vector of your choice as an expression/transfection-ready ORF clone. Not the clone you want?
