General description

Gel filtration chromatography is a well-known technique for measuring the size and molecular weight of proteins. It separates proteins based on their ability to diffuse into the pores of the resin. Larger proteins have more difficulty entering the resin pores, so they flow through the column more quickly than smaller proteins. As a result, the proteins are eluted from the column in order of decreasing molecular weight.

Application

Gel Filtration Markers Kit for Protein Molecular Weights 29,000-700,000 Da has been used:
  • for protein purification and analyses (gel-filtration experiments)
  • for size-exclusion chromatography/gel filtration chromatography of synaptoneurosome extract
  • for glycerol gradient centrifugation
  • to study glucocorticoid-induced lymphocytolysis as a model system for apoptosis within the immune system
  • to isolate Polygonatum odoratum lectin, which showed remarkable anti-HSV-II activity towards Vero cells, cytotoxicity towards human melanoma A375 cells and induced apoptosis in a caspase-dependent manner

Biochem/physiol Actions

The method described in the bulletin for determining molecular masses using gel filtration chromatography is a modified version of existing published techniques. The protein standards included in this kit may be compatible with other chromatographic systems like high-performance liquid chromatography (HPLC). However, certain buffer systems may affect the elution volumes of albumin and carbonic anhydrase. The proteins in this kit have a molecular mass range spanning from 29 kDa to 699 kDa.

Voltage-gated calcium channels conduct Ca(2+) ions in response to membrane depolarization. The resulting transient increase in cytoplasmic free calcium concentration is a critical trigger for the initiation of such vital responses as muscle contraction and transcription.
