for use with (Complex cell extracts, pure protein solution, 1D and 2D PAGE gels)

애플리케이션

The ProteoMass Guanidination Kit allows you to enhance MALDI-MS sensitivity, increase sequence coverage, and identify peptides with greater confidence. Following proteolytic digestion, peptides with C-terminal Arginine residues are ionized preferentially over peptides with C-terminal Lysine residues, leading to compromised sequence coverage and limited confidence during peptide mass fingerprint analysis. The ProteoMass Guanidination Kit efficiently and conveniently converts C-terminal Lysine residues to homoarginine, increasing MALDI signal strength and producing enhanced sequence coverage.

특징 및 장점

  • Identify more samples with greater accuracy and confidence
  • Increase throughput and save time - only 35 minutes to use the kit vs. 2 hours using traditional methods
  • Compatibility - compatible with 1D or 2D PAGE gel bands or spots, as well as complex cell extracts

기타 정보

One MS0100 kit is sufficient for 96 reactions.

A variety of N-glycans attached to protein are known to involve in many important biological functions. Endoplasmic reticulum (ER) and Golgi localized enzymes are responsible to this template-independent glycan synthesis resulting glycoforms at each asparagine residues. The regulation mechanism such

To investigate the early changes in protein function that induce micro-metastasis in early-stage non-small cell lung cancer, we conducted proteomic analysis of tissue that had been completely resected. We selected sixteen patients whose tumors were pathological stage I adenocarcinoma with

Group B Streptococcus pili are covalently linked structures assembled via a sortase-catalyzed transpeptidation mechanism involving specific residues and motifs. A sequence element containing a conserved glutamic acid, called the E-box, has been described to be involved in pilus formation. Although

Several studies have suggested that the emulsification properties associated with pectin obtained from sugar beet (Beta vulgaris) are due to the presence of a protein-pectin complex. Nevertheless, the identity of the protein has remained elusive. Pectin, extracted from sugar beet

Mutations in DJ-1 cause an autosomal recessive, early onset familial form of Parkinson disease (PD). However, little is presently known about the role of DJ-1 in the more common sporadic form of PD and in other age-related neurodegenerative diseases, such
