These antisera primarily detected a 145-kilodalton nuclear protein that bound double-stranded DNA.

The polypeptide products of this reaction included two major species of 220 and 28 kilodaltons.

These enzymes are single-chain proteins of 100-130 kilodaltons.

Kilo-u or kilo-amu would be awkward, so a protein molecule might be said to have a mass of 35 kilodaltons, or kDA.

With gel-filtration we separated neurotrophic activity in several fractions, which included marker proteins of 8, 22 and 30 kilodaltons.

One hundred and thirty kiloDalton PLC-beta4 was exclusively expressed in the nervous tissues including cerebellum and cerebrum, especially at very high levels in cerebellum.

The open reading frame consists of 2256 nucleotides and encodes a protein of 752 amino acids with a calculated molecular mass of 83 kilodaltons.

Immunoblotting showed that the antibody B1 recognized an antigen of approximately 100 kilodaltons and that B10 recognized an antigen of approximately 125 to 130 kilodaltons.

The gene for a second protein product (43 kilodaltons) was transcribed in the opposite direction, presumably under the control of a promoter in pBR322.
