1. An extended soluble PH20 hyaluronidase (esPH20), wherein:
- the esPH20 polypeptide exhibits hyaluronidase activity at neutral pH;
the esPH20 polypeptide is secreted when expressed in a mammalian cell;
the esPH20 polypeptide is soluble; and
the esPH20 polypeptide is selected from among;
a polypeptide that consists of the sequence of amino acids set forth as amino acid residues 36-495, 36-496, 36-497, 36-498, 36-499 or 36-500 of SEQ ID NO;
107;
ora polypeptide that contains amino acid substitutions in the sequence of amino acids set forth as amino acids 36-495, 36-496, 36-497, 36-498, 36-499 or 36-500 of SEQ ID NO;
107, whereby the amino acid-substituted polypeptide consists of a sequence of amino acids that has at least 95% sequence identity with the corresponding sequence of amino acids set forth as amino acids 36-495, 36-496, 36-497, 36-498, 36-499 or 36-500 of SEQ ID NO;
107.
