Il10^tm1Cgn

A 500 bp genomic fragment containing codons 5-55 was replaced with a linker containing a termination codon followed by a neomycin cassette. A termination codon was also introduced into exon 3. No IL10 activity was detectable by ELISA assays in supernatants of in vitro cultures of Con A-stimulated splenic T cells derived from homozygous mice following infection with the nematode N. brasiliensis.
