Form
Lyophilized powder
Note: We will preferentially ship the format that
we have in stock, however, if you have any special requirement for the format, please remark your
requirement when placing the order, we will prepare according to your demand.
Buffer
Lyophilized from a 0.2 μm filtered 20 mM Tris-HCl, 0.5 M NaCl, 6% Trehalose, pH 8.0
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw
cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature
and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized
form is 12 months at -20°C/-80°C.
Lead Time
Basically, we can dispatch the products out in 3-7 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Description
This Human MAPT recombinant protein was produced in mammalian cell, where the gene sequence encoding Human MAPT (1-441aa) was expressed with the N-terminal 10xHis-tag. The purity of this MAPT protein was greater than 95% by SDS-PAGE. The activity was validated.
Tau protein plays an important role in different stages of tauopathies. Its abnormal phosphorylation leads to defective axonal transport, synaptic loss and neuroinflammation as early signals of neurodegeneration. Tau protein tangles may be the manifestation of advanced disease, causing the loss of normal cell function and leading to the occurrence of the disease. At the same time, tau protein tangles can also shield many proteins with important functions and aggravate neurological damage. The more thorough the research on tau protein, the more helpful it is to understand degenerative neuropathy, and at the same time, it will be helpful for the treatment of this type of disease. Targeting the metabolism and function of tau protein as a drug target may have important implications for the targeted therapy of degenerative neuropathy. In clinical application, tau protein examination is of great value for evaluating AD, CJD, PART, etc.
