Custom Immunohistochemistry (IHC) Services In addition to
a large number of pre-formatted and customized paraffin-embedded slides,
cryosections and tissue microarrays, Creative
Biolabs also offers a comprehensive range of custom
immunohistochemistry (IHC) services from screening of IHC-good
antibodies to selection of the best tissue sections and IHC detection
methods.
Creative
Biolabs has established well-tested SOPs in optimizing IHC
staining conditions, which include different combinations of various
tissue fixation processes, antigen retrieval conditions, antibody
titration options, incubation time and washing stringency. We are
professional in both enzyme [alkaline phosphatase and peroxidase] and
fluorophore-based IHC visualization methods. Co-localization of multiple
antigens by multiplex staining is routinely performed. You can rely on
our extensive microscopic imaging experience in capturing the typical
staining results into high resolution digital images. Of note, we are
the only company in the international market that provides custom
service of screening for IHC-suitable monoclonal antibodies. Also, we
have unparalleled bioinformatics support in performing IHC studies. In
order to choose the right tissue types in IHC staining, we frequently
utilize the mRNA expression profile of a target antigen. The mRNA
expression information of most genes is widely available from various
public databases, such as http://cgap.nci.nih.gov/Genes. Also, protein
expression profiles from public resources are routinely employed; a good
example is Human Protein Atlas at http://www.proteinatlas.org/index.php.
Finally staining tissue sections are manually reviewed and annotated by
two staff pathologists in dependently. The terminology and ontology used
are in compliance with standards used in pathology and medical science.
In the end, a summary statement for each IHC staining project is
prepared. Comprehensive pathology consultation from our experienced
staff pathologists is also available upon request.Importantly,
with our proprietary technology, we are able to maximize the staining
signals even for antigens with extremely low expression levels. Many
researchers have also approached us for our ISH service offerings when
they wish to "double-stain" the tissues to simultaneously show both gene
and protein expression. | ||
