Jan 23, 2022 · The broad set of primary container solutions include vials, syringes, cartridges, and ampules among others. The most common primary containers for protein-based biologics are vials and prefilled syringes (PFS). Vials and PFS are available as glass or polymer, however vials used for commercial products remain predominantly glass.

Corning. These Costar® 1.7mL low binding microcentrifuge tubes feature a bonded polymer technology that reduces protein and nucleic acid binding, resulting in better sample recovery. They are made of natural (uncolored) polypropylene and are certified RNase-/DNase-free. -Supplied nonsterile and are.

entire vial was resuspended in 2% acetic acid to a final concentration of 1.722 M and the stock aliquoted into 0.5 ml low protein binding tubes for storage at 80 °C. For generation of the standard curve, an intermediate dilution of 312.5 nM heavy insulin was made with 2% acetic acid in low protein binding tubes, which was spiked into

Jan 01, 2016 · Another important cis-polyisoprenoid is natural rubber (NR), an important industrial biopolymer primarily produced from the Brazilian rubber tree (Hevea brasiliensis).NR possesses properties of superior resilience, heat dispersion, and abrasion resistance over synthetic rubber derived from petrochemicals, thereby being considered as an irreplaceable and strategically important industrial raw

Nov 02, 2018 · SBC is usually reported as the maximum amount of protein bound to a chromatography resin at given solvent and protein concentration conditions. In these experiments, an excess of protein is loaded to give a maximum protein binding capacity. Protein loss is often over 50%. The static binding capacity (SBC) value varies substantially depending on

Jan 23, 2015 · Although a major source of natural rubber is the rubber tree (Hevea brasiliensis), lettuce (Lactuca sativa) is also known to synthesize natural rubber. Here, we report that an unusual cis-prenyltransferase-like 2 (CPTL2) that lacks the conserved motifs of conventional cis-prenyltransferase is required for natural rubber biosynthesis in lettuce.

The protein concentrations analysed by the Lowry method in the 2 laboratories gave concordant results, but the correlations between protein and allergen concentrations were low. The protein concentration analysed by HPLC correlated with the allergen concentration, and gave better information on the allergenicity of the gloves.
