Useful for the chromatin research on the drosophila.

Anti Drosophila SSRP1 Polyclonal antibody
Anti Drosophila SPT16 Polyclonal antibody


 dSSRP1 and dSPT16 are a Drosophila counterpart of the FACT [Facilitates Chromatin Transcription] subunit. FACT consists of a heterodimer of SSRP1 and SPT16 and was identified as a factor that facilitates chromatin transcription in vitro. Further studies revealed that the factor also facilitates various chromatin transactions such as transcriptional regulation, DNA replication and histone replacement. The antibodies against dSSRP1 and dSPT16 are powerful tool for Western blot analyses, immunostaining, immunoprecipitation and chromatin immunopreciptation in studies using Drosophila.
