Utilizing our extensive archives of total protein samples, we offer Antibody screening on arrays of hundreds of our highly-characterized total protein samples. Linked to a database of their source clinical/pathology data, our protein samples are membrane-bound (nitrocellulose or PVDF), and are available for purchase or for services to screen your antibodies.

Cancerscreen 200
a human cancer screen of over 200 protein samples

Derived from our extensive total protein sample database, we offer our Cancerscreen 200 service ? this service is intended to serve as a rapid screen of antibodies, across a broad spectrum of human cancers , screening over 200 individual total proteins. Samples represent most major cancers and stages of cancer, including matched normal samples. Gel data is provided to document protein sample integrity.

A database of clinical/pathology information is included, along with a custom bioinformatics analysis.

Purchase a Cancerscreen 200 protein array blot. Includes one ready-to-use protein array blot, Sample Clinical/pathology database, and gel data documenting protein integrity.
$1,450 per blot

Let us screen your antibody on our Cancerscreen 200 protein array blot. A complete report is provided, including digital images, clinical/pathology database, and a custom bioinformatics relational analysis.
$1,950 per antibody

CancerScreen 200 Quantitative Analysis
Quantitative analysis of Phospho-p53 across multiple protein samples. The Red Circle indicates abundance of signal. The Green Cross Indicates less to an absence of signal.

The following analysis compares the intensity if HSI of the samples with abundant signal to the HIS of samples with absence of signal via intensity measurements.

Statistical analysis performed via intensity measurements to specific data structures, such as histology code, etc.

Intensity measurement from sample number 9 in red (Class 0), marked on dot blot picture.

Intensity measurement is calculated via the negative control (Green Line) and the Positive Control (Red Line) across 256 pixel range calculation of HIS (Hue, Saturation and Intensity)

Spotfire analysis from above statistical Dunn’s Comparison Intensity calculations v. Histology Code

Hue and Saturation measurement for three specific samples on the blot, sample 95 (36.4286), 4 (109.286) and 2 (182.143). These measurements provide a quantitative range of scores to compare antibody – protein affinity.
