The
patent pending process used in the Liquid Tissue® MS
Protein Prep Kit enables mass spectrometry-based discovery and
measurement
of protein biomarkers in archival tissue. It has been used to
identify over 2,000 proteins extracted from FFPE samples using
LC-MS/MS mass spectrometry*.
A protocol is available to detect differential protein expression
using iTRAQ™** labeling.
Download it here.
A standard preparation uses a lot less tissue than any other
published methods. The Liquid Tissue® MS Protein Prep Kit
is optimized for processing approximately 30,000 cells, the equivalent
of a 2 x 4 mm region from a 10 µm thick section of FFPE
tissue, and will yield 5-10 µg of total protein.
Make sure you are using
the most recent revision of
the instruction manual.

DIRECTOR™ Laser
Microdissection Slides—Direct non-contact
microdissection without plastic film or sticky
caps
Fast Forward Microdissection
- for the Leica LMD and the P.A.L.M. Zeiss systems
Watch the videos
showing the principles and the slides in use
The
unique DIRECTOR slides feature a proprietary energy transfer
coating that replaces plastic films or adhesives for direct non-contact
microdissection. This makes possible fast and precise harvesting
of even the most specific cellular features, from
fine,
subcellular features to larger regions of tissue.
DIRECTOR slides are compatible with commonly used gene and protein
expression analysis methods, and work with tissues or cells,
whether fresh, frozen or fixed (inc. standard formalin
fixed paraffin embedded (FFPE) tissue).
The slides are inert to a wide range of chemical
and thermal conditions, and can be autoclaved, and are stable
in
organic solvents such as xylenes. DIRECTOR slides will not epifluoresce,
making them ideally suited for applications requiring fluorescent
stains, as well as those applications requiring DIC or polarized
light. Tissue sections will adhere to the DIRECTOR
slides just as well as to any standard pathology glass slides,
without pretreatment.
The DIRECTOR slides are based on Laser Induced Forward Transfer
(LIFT), a non-contact microdissection technology utilizing a
thin energy
transfer coating. Laser energy is transferred to the transfer
coating, the coating is vaporized and the selected feature instantly
shot
into
the collection tube. You collect exactly what you see in the
microscope. The energy transfer coating absorbs the laser energy,
so the biomolecules
in the sample are not affected. Since the coating is completely
vaporized there is absolutely no contamination of your sample.

ProteoSOL™
Tissue Extraction System
Available from KPL,
Kirkegaard & Perry Laboratories, the ProteoSOLTM
Tissue Extraction Systemis based on the Liquid Tissue®
ID Protein Prep Kit. It is designed for the extraction of proteins
directly from formalin fixed paraffin-embedded (FFPE) tissue samples.
The system enables immunodetection of proteins in a membrane-based
assay. Samples processed with this system can be arrayed and detected
on a membrane using high-throughput detection methods. Immunodetection
with specific antibodies allows the direct comparison of a specific
protein across multiple samples in a single array.
*Please note that samples processed using
the ProteoSOL Tissue Extraction System are not suitable for analysis
using mass spectrometry or gel electrophoresis.
