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?Comment

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.Comment

Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.
The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
