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.
Lyophilized from a 0.2 μm filtered 20 mM Tris-HCl, 0.5 M NaCl, 6% Trehalose, pH 8.0
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.
Troubleshooting and FAQs
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.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Recombinant Macaca mulatta microtubule-associated protein tau (MAPT) is an active protein produced in mammalian cell lines. The gene encoding the 2-459aa of the Macaca mulatta MAPT was fused with the 10xHis-tag at the N-terminus and then cloned into the plasmid vector, finally transfected into the mammalian cells for subsequent expression. This recombinant MAPT protein was purified and reached over 95% in purity measured by SDS-PAGE. Its endotoxin is less than 1.0 EU/ug determined by the LAL method. Importantly, the activity of this protein has been validated in a functional ELISA in which it can bind the anti-MAPT recombinant antibody, with the EC50 of 2.464-3.979 ng/mL.

MAPT plays an important role in the occurrence and development of neuropathy-related diseases. The accumulation of hyperphosphorylated MAPT in neurons will cause neurofibrillary degeneration, which is associated with a variety of neurodegenerative diseases such as Alzheimer's disease (AD) and PD. Non-human primates (NHP) show high homology with humans in physiological function and drug metabolism. In particular, their brains are most similar to humans in structure and function. Therefore, scientists are hoping to be able to model human disease by building NHP models, especially in neuroscience. MAPT protein from Macaca mulatta goes beyond the limits of rodent studies.

Applications : Antigen

Review: I purchased lyophilized powder this time. After receiving the product, we dissolved it following the instructions, and it dissolved very well, and then through SDS detection, the purity was higher than the standard. After immunizing the mouse, coated the antigen, and several positive clones with good affinity were screened through ELISA. The antibody obtained from purified ascites has good specificity and high sensitivity. The overall performance of the product is good, the delivery is fast, and the COA report is very detailed!

Target Background

Promotes microtubule assembly and stability, and might be involved in the establishment and maintenance of neuronal polarity. The C-terminus binds axonal microtubules while the N-terminus binds neural plasma membrane components, suggesting that tau functions as a linker protein between both. Axonal polarity is predetermined by tau localization (in the neuronal cell) in the domain of the cell body defined by the centrosome. The short isoforms allow plasticity of the cytoskeleton whereas the longer isoforms may preferentially play a role in its stabilization.
