Human CTDSPL (CTD small phosphatase-like protein) ELISA KIT (HUFI05330)

CTDSPL encodes a small carboxy-terminal domain phosphatase that dephosphorylates the CTD of RNA polymerase II, fine-tuning the transition between transcription initiation and elongation. Loss of CTDSPL through hemizygous deletion at chromosome 3p21.3 or epigenetic silencing has been linked to small cell lung carcinoma, clear cell renal cell carcinoma, and acute myeloid leukemia, positioning the protein as a tumour suppressor of broad oncological interest.

Produced by Assay Genie for quantitative measurement of human CTDSPL, this ELISA kit supports investigation of transcriptional regulation, phosphatase signalling, and oncology biomarker discovery. The kit format is well suited to in vitro studies of cell lysates and research use only applications where reproducible quantification of CTDSPL protein is required across experimental cohorts.
