Differential Protein Expression Analysis

HCP Antibody Coverage Analysis

Melanie Classic / DIGE

Melanie Coverage

For scientists investigating biological processes by characterizing samples in terms of relative protein abundance and posttranslational modifications.   For scientists involved in the development or use of immunoassays aimed at monitoring Host Cell Protein (HCP) impurities in biopharmaceutical products.
Designed to detect statistically significant differences in protein expression between experimental groups, with high objectivity, sensitivity and confidence. Designed to analyze 2D-PAGE based coverage, i.e. the percentage of immunodetection that an antibody reagent offers for the total population of HCPs.
Supports images from a wide range of 2D-PAGE based methods:
• Conventional 2-DE
• 2D Differential in Gel Electrophoresis (2D-DIGE)
• Other multiplexed technologies without internal standard
Supports images from a wide range of 2D-PAGE based methods:
• Conventional 2-DE followed by 2D Western blotting
• 2D Differential In Blot Electrophoresis (2D-DIBE)
• Antibody affinity chromatography followed by 2D-DIGE

Still innovating after 30 years!

We’re thrilled to present our new and expanded Melanie 9! Its new Coverage module and a range of added functionality and clever improvements will help you draw more reliable conclusions from your 2D electrophoresis gels and Western blots.

If you are looking for tools to characterize HCP impurities in biopharmaceutical products, check out our module for Coverage Analysis. Are you rather wondering whether your protein expression differences are real? Don’t guess; our Differential Expression Analysis solution saves you time and money otherwise wasted chasing false positives.

Considering an upgrade? Here are the main new features:

  • Coverage module solely dedicated to HCP antibody coverage analysis
  • Principal component analysis (PCA)
  • Dedicated interface to define pI and MW markers
  • Redesigned spot editing tools that work in the 3D view as well
  • More…
