AHP2067 specifically recognises an epitope within the N-terminal (NT) region of human PTBP1, otherwise known as polypyrimidine tract-binding protein 1, a multi-functional, ubiquitously expressed heterogeneous nuclear ribonucleoprotein (hnRNP), implicated in pre-mRNA processing, and in mRNA metabolism and transport.
Studies have shown PTBP1 is highly over-expressed in glioma and, along with its brain-specific homologue PTBP2, acts as a regulator of neural precursor cell differentiation.

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.
Western Blotting
AHP2067 detects a band of approximately 60-65kDa in Jurkat cell lysates.
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
18 months from date of despatch.
Antiserum Preparation
Antiserum to human PTBP1 (NT) was raised by repeated immunisation of goats with highly purified antigen. Purified IgG was prepared by affinity chromatography.
