Human Transportin-3 (TNPO3) ELISA Kit,Abbkine,KTE60181
• Do not mix components from different kit lots or use reagents beyond the kit expiration date.• Allow all reagents to warm to room temperature for at least 30 minutes before opening.• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination. • Unused wells must be kept desiccated at 4 °C in the sealed bag provided.• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.• It is recommended that all samples and standards be assayed in duplicate or triplicate.

Scientific Background
TNPO3 is a nuclear import receptor for serine/arginine-rich (SR) proteins, which are essential precursor-mRNA splicing factors.By yeast 2-hybrid analysis using the RS domain of the E2 protein of human papillomavirus (HPV)-5 as bait, Lai et al. (2000) cloned a TNPO3 splice variant, TRNSR2, from a HeLa cell cDNA library. The deduced 923-amino acid TRNSR2 protein lacks 2 regions of about 30 amino acids each found in the TRNSR protein identified by Kataoka et al. (1999). Northern blot analysis detected ubiquitous expression of a 4.5-kb transcript, with highest expression in testis. Epitope-tagged TRNSR2 localized throughout transfected HeLa cells, but a mutant lacking the N-terminal region colocalized with splicing factor SC35 (SFRS2) in nuclear speckles.
