Features & Benefits
Human Tau-tubulin kinase 2 (TTBK2) ELISA Kit has high sensitivity and excellent specificity for detection of Human TTBK2. No significant cross-reactivity or interference between Human TTBK2 and analogues was observed.
Background
TTBK2 produces a 5.6-kb transcript in which the longest open reading frame is 3,732 nucleotides, encoding a protein of 1,244 amino acids. The gene is alternatively spliced, with ubiquitous expression in human adult and fetal tissues. The N-terminus of TTBK2 encodes a serine-threonine-tyrosine kinase domain, and a C-terminal region shows homology to TTBK1. TTBK2 was expressed in all brain regions in human, rat, and mouse tissue. There was particularly high expression in Purkinje cells of the cerebellum, granular cell layer, hippocampus, midbrain, and substantia nigra. Lower expression was seen in the cortex of human, rat, and mouse brains.2 TTBK2 phosphorylation sites in tau (ser208 and ser210) are priming sites for the phosphorylation of tau by GSK-3-beta, which influences tau pathology.
This Tau-tubulin kinase 2 (TTBK2) ELISA kit is validated for use with Cell culture supernatants, Serum, Plasma, Other biological fluids. Samples should be collected, processed, and stored correctly to preserve analyte integrity — avoid repeated freeze-thaw cycles and centrifuge to remove particulates before use. Dilute samples exceeding the kit's detection range using the supplied assay diluent. Hemolytic, icteric, or lipemic samples may affect assay performance and should be tested with caution.
This is a sandwich ELISA kit employing an HRP (horseradish peroxidase)-conjugated secondary antibody paired with a TMB (3,3′,5,5′-tetramethylbenzidine) colorimetric substrate. In the sandwich format, the target analyte Tau-tubulin kinase 2 (TTBK2) captured on the microplate surface is detected by the conjugated antibody, generating a colorimetric signal proportional to analyte concentration. The reaction is stopped and absorbance measured at 450 nm on a standard microplate reader.
The complete protocol, from sample addition to final plate reading, requires approximately 3–5 hours. This includes two incubation periods (analyte binding and detection antibody steps), intermediate wash cycles to remove unbound material, 15–30 minutes of TMB substrate development, and final stop-solution addition before absorbance reading. Exact timing will vary with experience level and the number of samples processed in parallel.
Required equipment: (1) a microplate spectrophotometer capable of reading absorbance at 450 nm (reference wavelength 540–570 nm recommended for background correction); (2) precision single-channel or multichannel pipettes; (3) a plate washer or multichannel aspirator; (4) a microcentrifuge for sample clarification; and (5) a 37°C incubator or stable room-temperature environment. No fluorescence or luminescence reader is required — standard colorimetric plate readers are fully compatible with this kit.
This ELISA kit is formally validated for Human. Cross-reactivity with species not listed in the specification has not been independently characterized. Variability in protein sequence homology across species means that performance in unlisted species cannot be guaranteed without additional validation. For cross-species detection requirements or non-standard sample matrices, please contact BioHippo support or refer to the manufacturer's technical team for guidance.
