Eppendorf® Protein DNA LoBind™ Microcentrifuge Tubes¬†are specifically designed for use in proteomics or other fields of protein research (antibodies, cell biology, peptide drugs etc.), where samples tend to be very small and sample recovery is vital. LoBind tubes improve recovery by reducing sample-to-tube binding‚Äîwithout the use of any additives or coatings. A combination of specially developed technology and the purest, select polypropylene results in tube binding that ensures minimal loss (<3%). Enzymes remain active, and they are not denatured by any tube-surface interactions. Rated to 18,000 x g.¬†Ideal¬†for preparation and storage of low concentrated protein, peptide, antibody or virus samples.
