- sequence comparison typically one sequence acts as a reference sequence, to which test sequences are compared.
- test and reference sequences are input into a computer, subsequence coordinates are designated, if necessary, and sequence algorithm program parameters are designated.
- sequence comparison algorithm then calculates the percent sequence identity for the test sequence(s) relative to the reference sequence, based on the designated program parameters.
- Optimal alignment of sequences for comparison can be conducted, e.g, by the local homology algorithm of Smith & Waterman, Adv. Appl. Math. 2:482 (1981), by the homology alignment algorithm of Needleman & Wunsch, J. Mol.

- Software for performing BLAST analyses is publicly available through the National Center for Biotechnology Information.
- This algorithm involves first identifying high scoring sequence pairs (HSPs) by identifying short words of length W in the query sequence, which either match or satisfy some positive-valued threshold score T when aligned with a word of the same length in a database sequence. T is referred to as the neighborhood word score threshold (Altschul etal ., supra).
- HSPs high scoring sequence pairs
- T is referred to as the neighborhood word score threshold (Altschul etal ., supra).
- These initial neighborhood word hits act as seeds for initiating searches to find longer HSPs containing them.
- the word hits are then extended in both directions along each sequence for as far as the cumulative alignment score can be increased.
- Cumulative scores are calculated using, for nucleotide sequences, the parameters M (reward score for a pair of matching residues; always > 0) and N (penalty score for mismatching residues; always ⁇ 0).
- M forward score for a pair of matching residues; always > 0
- N penalty score for mismatching residues; always ⁇ 0.
- a scoring matrix is used to calculate the cumulative score. Extension of the word hits in each direction are halted when: the cumulative alignment score falls off by the quantity X from its maximum achieved value; the cumulative score goes to zero or below, due to the accumulation of one or more negative-scoring residue alignments; or the end of either sequence is reached.
- the BLAST algorithm parameters W, T, and X determine the sensitivity and speed of the alignment.
- the BLASTP program uses as defaults a word length (W) of 3, an expectation (E) of 10, and the BLOSUM62 scoring matrix (see Henikoff & Henikoff, Proc. Natl. Acad. Sci. USA 89:10915 (1989)).

- Antibody light chains of vertebrate species can be assigned to one of two clearly distinct types, namely kappa and lambda, based on the amino acid sequences of their constant domains. Accordingly, the antibodies provided herein can contain a kappa or lambda light chain constant domain. According to particular embodiments, the antibodies of the invention include heavy and/or light chain constant regions from rat or human antibodies.
- antibodies contain an antigen-binding region that is made up of a light chain variable region (VL) and a heavy chain variable region (VH), each of which contains three domains (i.e., complementarity determining regions 1 (CDR1), CDR2 and CDR3.
- a “CDR” refers to one of three hypervariable regions (HCDR1, HCDR2 or HCDR3) within the non- framework region of the immunoglobulin (Ig or antibody) VH b-sheet framework, or one of three hypervariable regions (LCDR1, LCDR2 or LCDR3) within the non- framework region of the antibody VL b-sheet framework.
- CDRs are variable region sequences interspersed within the framework region sequences.
- CDR regions are well known to those skilled in the art and have been defined by, for example, Kabat as the regions of most hypervariability within the antibody variable (V) domains (Kabat etal, J. Biol. Chem. 252:6609-6616 (1977); Kabat, A civ. Prot. Chem. 32:1-75 (1978)).
- CDR region sequences also have been defined structurally by Chothia as those residues that are not part of the conserved b-sheet framework, and thus are able to adapt different conformations (Chothia and Lesk, J. Mol. Biol. 196:901-917 (1987)). Both terminologies are well recognized in the art.
- CDR region sequences have also been defined by AbM, Contact and IMGT. Exemplary CDR region sequences are illustrated herein, for example, in the Sequence Listing, and tables provided in the Examples below. The positions of CDRs within a canonical antibody variable region have been determined by comparison of numerous structures (Al-Lazikani etal, J. Mol. Biol. 273:927-948 (1997); Morea et ah, Methods 20:267-279 (2000)).
- the light chain variable region CDR1 domain is interchangeably referred to herein as LCDR1 or VL CDR1.
- the light chain variable region CDR2 domain is interchangeably referred to herein as LCDR2 or VL CDR2.
- the light chain variable region CDR3 domain is interchangeably referred to herein as LCDR3 or VL CDR3.
- the heavy chain variable region CDR1 domain is interchangeably referred to herein as HCDR1 or VH CDR1.
- the heavy chain variable region CDR2 domain is interchangeably referred to herein as HCDR2 or VH CDR2.
- the heavy chain variable region CDR1 domain is interchangeably referred to herein as HCDR3 or VH CDR3.
- hypervariable region such as a VH or VL

- VL VL
- hypervariable region delineations are in use and are encompassed herein.
- Kabat CDRs are based on sequence variability and are the most commonly used (see, e.g., Kabat etal. , Sequences of Proteins of Immunological Interest. 5th Ed. Public Health Service, National Institutes of Health, Bethesda, MD.
- Chothia refers instead to the location of the structural loops (see, e.g., Chothia and Lesk, ./. Mol. Biol. 196:901-917 (1987)).
- the end of the Chothia CDR-HCDR1 loop when numbered using the Rabat numbering convention varies between H32 and H34 depending on the length of the loop (this is because the Rabat numbering scheme places the insertions at H35A and H35B; if neither 35 A nor 35B is present, the loop ends at 32; if only 35 A is present, the loop ends at 33; if both 35A and 35B are present, the loop ends at 34).
- the “AbM” hypervariable regions represent a compromise between the Rabat CDRs and Chothia structural loops, and are used by Oxford Molecular’s AbM antibody modeling software (see, e.g, Martin, in Antibody Engineering. Vol. 2, Chapter 3, Springer Verlag). “Contact” hypervariable regions are based on an analysis of the available complex crystal structures.
- ImMunoGeneTics (IMGT) Information System ® (Lafranc etal. , Dev.
- IMGT immunoglobulins
- TR T cell receptors
- MHC major histocompatibility complex
- the CDRs are referred to in terms of both the amino acid sequence and the location within the light or heavy chain.
- location of the CDRs within the structure of the immunoglobulin variable domain is conserved between species and present in structures called loops, by using numbering systems that align variable domain sequences according to structural features, CDR and framework residues and are readily identified.
- This information can be used in grafting and replacement of CDR residues from immunoglobulins of one species into an acceptor framework from, typically, a human antibody.
- An additional numbering system (AHon) has been developed by Honegger and Pluckthun, ./. Mol. Biol. 309: 657-670 (2001).
- the numbering system including, for example, the Rabat numbering and the IMGT unique numbering system, is well known to one skilled in the art (see, e.g., Rabat, supra ; Chothia and Lesk, supra ; Martin, supra ; Lefranc et al. , supra).
- An Exemplary system shown herein, combines Rabat and Chothia.

- CDR sequences reflecting each of the above numbering schemes, are provided herein, including in the Sequence Listing.

- the constant region may contain the CHI, CH2 and CH3 regions of the heavy chain and the CL region of the light chain.
- FR residues are those variable region residues flanking the CDRs. FR residues are present, for example, in chimeric, humanized, human, domain antibodies, diabodies, linear antibodies, and bispecific antibodies. FR residues are those variable domain residues other than the hypervariable region residues or CDR residues.
