HCP Profiling Analysis

Our HCP Profiling analyses detect, quantify and compare HCP compositions of 3 HCP samples in 1 test. The data report includes individual HCP image and overlay image of different HCP samples, giving you the direct visualization and comparison of HCP compositions, modifications and fragmentations that no other platform could achieve. In addition, the quantitation analysis provides spot counting, similarity analysis, total HCP and DS quantity. Our LCMSMS and mass spectrometry services will provide the protein identity of HCPs. This platform has been successfully applied in the following areas:

  1. Compare batch-to-batch HCP profile
  2. Track purification process

Each analysis can test up to 3 HCP samples simultaneously. For projects with more than 3 samples, Cross-gel analysis will be performed using customers pre-set control, or default internal standard.

Each report has two components:

A. HCP Image analysis

Gel images of each sample and overlay of two sample images will be generated. In the 2-color overlay image, spots with green, red and yellow color indicate decreased, increased and similar expression, respectively.


HCP Profiling Analysis: 2D image of HCP-1


HCP Profiling Analysis: 2D image of HCP-2


HCP Profiling Analysis: 2D image of HCP-3

HCP-1 / HCP-2

HCP Profiling Analysis: Overlay image of HCP-1 and HCP-2

HCP-1 / HCP-2 / HCP-3

HCP Profiling Analysis: Triple color overlay image of HCP-1, 2 and 3

B. HCP Quantitative analysis

Spot counting of each sample: Total number of spots for each sample and presence/absence of each spot area
Similarity analysis: Default or customer requested fold cutoff will be used to assess the % similarity between samples

Sample Info

Please follow these general principles regarding biohazardous materials and buffer condition in getting your samples ready.

Protein amount for each gel: 20-50 µg of total protein from each sample.

Protein concentration: 5-20 mg/ml is preferred.

Buffer: Please feel free to submit samples in whichever buffer that you would normally use. The standard sample preparation is covered by the DIGE gel cost. Such samples should have protein concentration in the range of 5-20 mg/ml. Additional charge may apply on samples that require extensive amount of the extra work such as protein eluting, concentrating, buffer exchange or serum abundant protein depletion.

Sample type: Please inform our scientists about your sample type. We will send you additional tips for each sample type.
