    Tools for identifying/verifying protein (without accession number)

    If I have a series of protein sequences (experimentally obtained) that yield no results from BLAST, are there any other online/software tools that can be used to either identify or verify that these proteins exist?

    If you obtained these sequences experimentally then they definitely exist

    Have you tried psi-blast or better yet delta-blast @NCBI?

      They're not annotated in databases such as UniProt/Swiss-Prot so I'm not sure how I can "prove" that they are indeed real and transcribed from genes.

      All I have are the protein sequences themselves though, won't I need accession numbers or ID to run them through psi/delta-blast?

        You just need fasta sequence for doing delta- or psi-blast. You can limit your search against swissprot or refseq if you want well annotated proteins.

          Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
          by SEQadmin2



          Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

          Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating

          New Genomics Technologies Take Aim at Long-Standing Limits
          by SEQadmin2


          Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

          We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
