Abstract
The present invention relates generally to novel recombinant polypeptides of Bahia grass pollen and to genetic sequences encoding same. More particularly, the present invention is directed to Pas n 1 polypeptides and derivatives, and fragments thereof and genetic sequences encoding same. The molecules of the present invention are useful in a range of therapeutic, prophylactic and diagnostic applications including, but not limited to, applications in the context of conditions characterized by an aberrant, inappropriate or otherwise unwanted immune response to the Bahia grass pollen.
Claims9
A non-glycosylated polypeptide comprising an amino acid sequence as set forth in SEQ ID NO:
- 4, or an amino acid sequence having at least 95%, 96%, 97%, 98% or 99% or more sequence identity to the entire amino acid sequence of SEQ ID NO:
- 4.
A diagnostic kit comprising a non-glycosylated polypeptide that comprises an amino acid sequence as set forth in SEQ ID NO:
- 4, or an amino acid sequence having at least 95%, 96%, 97%, 98% or 99% or more sequence identity to the entire amino acid sequence of SEQ ID NO:
- 4;
- and a secondary antibody for detecting a mammalian antibody to the non-glycosylated polypeptide.
A method of detecting an antibody to Pas n 1 in a mammal, said method comprising contacting a biological sample obtained from a mammal with a non-glycosylated polypeptide that comprises an amino acid sequence as set forth in SEQ ID NO:
- 4, or an amino acid sequence having at least 95%, 96%, 97%, 98% or 99% or more sequence identity to the entire amino acid sequence of SEQ ID NO:
- 4, thereby forming a complex between the antibody and the non-glycosylated polypeptide.
