AHP2174 recognises CD294, also known as chemoattractant receptor homologous molecule expressed on Th2 cells (CRTH2) and GRP44.
CD294 is a G protein-coupled receptor which has a high affinity for prostaglandin D2 (PGD2).
CD294 is predominantly expressed on Th2 cells, basophils and eosinophils, and its activation by PDG2 mediates chemotaxis of these cells to inflammatory sites. CD294 may be a useful marker for Th2 cells, and enhances their function and signalling with a possible role in Th2 cell differentiation.
PGD2 is thought to contribute to bronchoconstriction, eosinophilia and mucus production in allergic asthma, and CD294 may contribute to this disease.

Where this product has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the product for use in their own system using appropriate negative/positive controls.
Immunohistology
*This product does not require protein digestion pre-treatment of paraffin sections e.g. trypsin or pronase. This product requires antigen retrieval using heat treatment prior to staining of paraffin sections.
Sodium citrate buffer pH 6.0 is recommended for this purpose.
Storage
Store at +4oC or at -20oC if preferred.
Storage in frost-free freezers is not recommended.
This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.
Shelf Life
12 months from date of despatch.
Antiserum Preparation
Antisera to human CD294 were raised by repeated immunisation of rabbits with highly purified antigen. Purified IgG prepared from whole serum by affinity chromatography.
