* 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 degree 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.

Background: QKI belongs to a family of RNA-binding proteins called STAR proteins for Signal Transduction and Activation of RNA. They have an HNRNPK homology (KH) domain embedded in a 200-amino acid region called the GSG domain. Other members of this family include SAM68 (KHDRBS1) and SF1. The QKI gene is implicated as being important in schizophrenia, and QKI controls translation of many oligodendrocyte-related genes.The balance between the nuclear and cytoplasmic isoforms of Qk1 controlled the nuclear export of Mbp mRNAs and the cellular localization of the 17- and 21.5-kD Mbp isoforms. Overexpression of Qki-5 in cultured rodent oligodendrocytes recreated the Mbp defects observed in qk(v) mice, with retention of Mbp in the nucleus.
NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this gene is an RNA-binding protein that regulates pre-mRNA splicing, export of mRNAs from the nucleus, protein translation, and mRNA stability. The encoded protein is involved in myelinization and oligodendrocyte differentiation and may play a role in schizophrenia. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2014]
Uniprot Description
QKI: RNA-binding protein that plays a central role in myelinization. Binds to the 5'-NACUAAY-N(1,20)-UAAY-3' RNA core sequence. Acts by regulating pre-mRNA splicing, mRNA export, mRNA stability and protein translation. Required to protect and promote stability of mRNAs such as MBP and CDKN1B. Regulator of oligodendrocyte differentiation and maturation in the brain that may play a role in myelin and oligodendrocyte dysfunction in schizophrenia. Participates in mRNA transport by regulating the nuclear export of MBP mRNA. Also involved in regulation of mRNA splicing of MAG pre-mRNA. Acts as a translational repressor. 6 isoforms of the human protein are produced by alternative splicing.

Product Notes
The Human QKI qki (Catalog #AAA9714671) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA9714671 ELISA Kit recognizes Human QKI. It is sometimes possible for the material contained within the vial of "Protein Quaking (QKI), ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
