General description

The protein standard mix is a calibration standard to test and monitor performance of size exclusion chromatography (SEC) columns. It is a lyophilized mixture of molecular weight markers ranging from 15 kDa to 600 kDa.

Components

Thyroglobulin bovine MW ~ 670 000 Da

γ-globulins from bovine blood MW ~ 150 000 Da

Ovalbumin MW~ 44 300 Da

Ribonuclease A type I-A MW ~ 13 700 Da

p-aminobenzoic acid (pABA) MW ~ 137 Da

Application

This analytical standard is used for the following:
  • Evaluation of selectivity and separation efficiency of size exclusion chromatography (SEC) to separate intact proteins by varying flow rate, size of silica particles and pore sizes in the column
  • Simultaneous determination of oligomerized and nitrated proteins by size exclusion chromatography-high performance liquid chromatography-diode array detection (SEC-HPLC-DAD)
  • Molecular weight separation of proteins by size-exclusion chromatography, formed upon O3 and NO2 induced oxidation, nitration, and oligomerization of bovine serum albumin (BSA) as a model protein
  • Estimation of molecular masses of two recombinant proteins— TNF fluorescent sensor (BTN-Kat) and fluorescent sensor-inhibitor (ITN-Kat), by size exclusion chromatography (SEC) to evaluate their ability of binding and neutralizing tumor necrosis factor (TNF) in vitro and further serving as imaging labels for non-invasive analysis

In this work, we characterized 2 novel insecticidal proteins; Vip3Ab1 and Vip3Bc1. These proteins display unique insecticidal spectra and have differential rates of processing by lepidopteran digestive enzymes. Furthermore, we have found that both proteins exist as tetramers in their
