Anti-STK31 Rabbit Polyclonal Antibody for WB, ELISA - Q9BXU1

Core Product Specifications and Parameters

Biological Background: STK31 Function and Localization

• STK31 (Serine/threonine-protein kinase 31), also known as TDRD8 or Sugen kinase 396 (SGK396), is a member of the serine/threonine protein kinase family.
• The protein is characterized by an ATP-binding site and a nucleotide-binding domain, indicative of its kinase and transferase activities.
• The STK31 gene undergoes alternative splicing, producing multiple isoforms that may have distinct functional roles.
• Expression of STK31 is highly tissue-specific, with protein expression restricted to the testis.
• Structural features include a coiled coil domain, suggesting potential protein-protein interaction capabilities.
• The human STK31 protein has a calculated molecular weight of approximately 116 kDa (UniProt: 115,694 Da) and serves as a reference proteome component.

Experimental Guidance and Technical Tips

• The immunogen used is a recombinant fragment spanning amino acids 890–1019 of human STK31. For Western blot (WB), expect a band near 116 kDa; use testis lysates as a positive control based on tissue specificity.
• For ELISA, consider using the recombinant immunogen as a coating antigen and test antibody reactivity against native protein in testis extracts.
• Given the polyclonal nature of the antibody and cross-reactivity with mouse and rat, validate specificity in species-specific testis samples to confirm suitability for cross-species studies.
• Note that alternative splicing may produce additional bands; confirm identity via mass spectrometry or isoform-specific probes if needed.
