Advanced searches

Sequence search options

Chains: Search for a sequence across complete chains
Sequence fragment:		Chains:	Both Heavy Light

Regions: Choose CDR definition to search by canonical or by sequence within a region

CDRs: Specify sequence / length / canonical class
	CDR	Length	Canonical Class
L1
L2
L3
H1
H2
H3			No Classes
Framework: Specify sequence / length
	Framework	Length
Framework L1
Framework L2
Framework L3
Framework L4
Framework H1
Framework H2
Framework H3
Framework H4

Residues: Search for specific residues at numbered positions
Specify residue number and type:		Combine with:	AND	OR
(e.g. L1:D or multiple entries L1:D L2:I)		Numbering:	Kabat	Chothia

Structural search options

Search only PDB data using actual structural constraints
Residue type must fall within a specified distance of a selected Chothia-numbered position
Chothia-numbered position	Amino acid	Distance (Angstroms)


Search all data using average structure distance constraints
Residue type must fall within a specified average distance (plus a number of standard deviations) of a Chothia-numbered position
Chothia-numbered position	Amino acid	Distance (Angstroms)	Number of standard deviations
