    Abstract: The present disclosure provides an asymmetric mixed antibody comprising two heavy chains or heavy chain fragments each comprising at least a variable region, a hinge region and a CH1 domain, wherein a first heavy chain or fragment thereof is a class IgG4 and has: a the inter-chain cysteine at position 127, numbered according to the Kabat numbering system, in the CH1 domain is substituted with another amino acid; and b optionally one or more of the amino acids positioned in the upper hinge region is substituted with cysteine, and wherein the second heavy chain or fragment thereof is characterised in that part or all of the chain has a different amino acid sequence to said first heavy chain in at least the region outside the variable region (for example the constant region), formulations comprising the same, therapeutic used of both of the above, and processes for preparing the antibodies and formulation.

    Abstract: The present invention provides an antibody of the class IgG4 comprising at least one heavy chain which comprises a CH1 domain and a hinge region, wherein in each heavy chain: a. the inter-chain cysteine at position 127, numbered according to the Kabat numbering system, in the CH1 domain is substituted with another amino acid; and b. one or more of the amino acids positioned in the upper hinge region is substituted with cysteine.

    Abstract: A recombinant gram-negative bacterial cell comprising one or more of the following mutated protease genes: a. a mutated Tsp gene, wherein the mutated Tsp gene encodes a Tsp protein having reduced protease activity or is a knockout mutated Tsp gene; b. a mutated ptr gene, wherein the mutated ptr gene encodes a Protease III protein having reduced protease activity or is a knockout mutated ptr gene; and c. a mutated DegP gene encoding a DegP protein having chaperone activity and reduced protease activity; wherein the cell is isogenic to a wild-type bacterial cell except for the mutated Tsp gene and/or mutated ptr gene and/or mutated Deg P gene and optionally a polynucleotide sequence encoding a protein of interest.

    Abstract: The present invention provides an antibody Fab or Fab' fragment to which at least one effector molecule is attached characterized in that the heavy chain in the fragment is not covalently bonded to the light chain and both the interchain cysteine of C L and the interchain cysteine of C H 1 have been replaced with another amino acid.
