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

Human telomeres contain the repeat DNA sequence 5'-d(TTAGGG), with duplex regions that are several kilobases long terminating in a 3' single-stranded overhang. The structure of the single-stranded overhang is not known with certainty, with disparate models proposed in the literature.
