The quest to characterize novel proteins can be elusive. For many researchers working in specialized model organisms such as insects, fish, worms, parasites, and plants, purchasing pre-made antibodies just simply isn’t an option.

Custom polyclonal antibodies allow you to specify, validate, and visualize specific protein targets

  • In a research study conducted by Kolosov et al., generating three custom polyclonal antibodies (pAbs) presented an ideal solution to the problem of detecting and characterizing novel proteins. Since pAbs recognize multiple epitopes of the same target protein, developing his own custom antibodies using GenScript’s popular pAb service maximized success of detecting the proteins of interest.

Uncovering how sea lamprey adapt to survive in habitats of varying salinity levels

  • Sea lamprey (Petromyzon marinus) is a parasitic fish that is able to survive in waters that vary widely in salinity levels. Post-metamorphosis, mature P. marinus reside primarily in seawater before returning to freshwater habitats to reproduce. As larvae, however, P. marinus can only tolerate living in freshwater within a strictly limited salinity range. As a result, this adaptation for surviving in aquatic habitats of varying ionic strength depends greatly on the stage of this organism’s life cycle.
  • To understand the molecular physiology behind P. marinus’ unique osmo/ionoregulation ability that enabled these fish to maintain stable serum ion levels while residing in habitats of varying ionic strength. Their research focused on the tight junction (TJ) proteins in larval sea lamprey that are responsible for paracellular solute movement across tissue-water barriers.
