               1. A DNA polynucleotide, or combination of DNA polynucleotides, encoding an anti-CD37 antibody which binds to human CD37, wherein the antibody comprises a variable heavy chain (VH) region and a variable light chain (VL) region selected from the group consisting of: 
            (i) a VH region comprising CDR1, CDR2, and CDR3 sequences comprising the amino acid sequences set forth in SEQ ID NOs: 16, 17, and 18, respectively, and a VL region comprising CDR1, CDR2, and CDR3 sequences comprising the amino acid sequences set forth in SEQ ID NO: 20, the sequence KAS, and SEQ ID NO: 21, respectively; 
                (ii) a VH region comprising CDR1, CDR2, and CDR3 sequences comprising the amino acid sequences set forth in SEQ ID NOs: 9, 10, and 11, respectively, and a variable light chain (VL) region comprising CDR1, CDR2, and CDR3 sequences comprising the amino acid sequences set forth in SEQ ID NO: 13, the sequence AAS, and SEQ ID NO: 14, respectively; 
                (iii) a VH region comprising CDR1, CDR2, and CDR3 sequences comprising the amino acid sequences set forth in SEQ ID NOs: 23, 24, and 25, respectively, and a VL region comprising CDR1, CDR2, and CDR3 sequences comprising the amino acid sequences set forth in SEQ ID NO: 27, the sequence YAS, and SEQ ID NO: 28, respectively; 
                (iv) a VH region comprising CDR1, CDR2, and CDR3 sequences comprising the amino acid sequences set forth in SEQ ID NOs: 23, 24, and 25, respectively, and a VL region comprising CDR1, CDR2, and CDR3 sequences comprising the amino acid sequences set forth in SEQ ID NO: 27, the sequence YAS, and SEQ ID NO: 31, respectively; and 
                (v) a VH region comprising CDR1, CDR2, and CDR3 sequences comprising the amino acid sequences set forth in SEQ ID NOs: 2, 3, and 4, respectively, and a VL region comprising CDR1, CDR2, and CDR3 sequences comprising the amino acid sequences set forth in SEQ ID NO: 6, the sequence EAS, and SEQ ID NO: 7, respectively; 
                wherein the antibody of any one of (i)-(v) optionally comprises an Fc region comprising at least one amino acid substitution selected from the group consisting of: E430G, E345K, E430S, E430F, E430T, E345Q, E345R, E345Y, S440Y and S440W; 
                wherein optionally the Fc region further comprises a K409R or F405L mutation, and 
                wherein the numbering of positions is according to the EU numbering system.
