kil·o·base (kb),

(kil'ō-bās),
Unit used in designating the length of a nucleic acid sequence; 1 kb equals a sequence of 1000 purine or pyrimidine bases.

kilobase (kb)

a length of nucleic acid equal to 1000 bases or nucleotides.

kilobase

A unit of measurement of the length of a DNA or RNA sequence equal to 1000 base pairs of DNA or 1000 bases of RNA.

kilobase (kb)

1000 BASES of DNA or RNA, used as a unit of length of single-stranded molecules. The kilobase is often also used as the unit of length for double-stranded molecules, though these should more correctly be measured in kilobase pairs (kbp).

kilobase

a unit of size for nucleic acids, being 1000 nucleotide bases for single-stranded nucleic acids or 1000 nucleotide base pairs in the case of double-stranded nucleic acids. Abbreviated kb or kbp.

The result is sequence information over extremely long "reads" ranging from hundreds of kilobases to a megabase, where the sample's valuable structural information is preserved.
Pathogenic copy number changes smaller than approximately 5-10 Mb are not detectable; however, recent advances in chromosomal microarray (CMA) [2a] analysis now allow the detection of chromosomal deletions and duplications at much higher resolutions (down to only a few kilobases, depending on the microarray), producing a higher diagnostic yield.
