The choice of signal peptide can have a profound impact on the yield and quality of the expressed protein. While native signal peptides can be effective, engineered or optimized ones, such as the IgKVIII tag, which is a mammalian signal peptide that allows for secretion of proteins into the extracellular space, are often employed. This IgKVIII tag is particularly useful for driving secretion. The literature further supports the utility of various signal peptides, with the Signal Peptide Database serving as a valuable resource for identifying and analyzing these sequences. Databases like UniProtKB, which provides information on proteins such as Protein Light chain kappa from *Mus musculus*, can also offer insights into naturally occurring signal peptidesFirstly, we often, but not always, use a genericmammalian signal peptide of Ig kappa (Igk) and wondered if the native signal peptide might be preferred..
