Formulation
Lyophilized from a 0.2 μm filtered solution of 10 mM Hepes, 150 mM NaCl, 1 mM DTT with 5% trehalose, pH 7.4.
Expression System
E.Coli
Expression Region
1-321
Purity
Greater than 90% as determined by SDS-PAGE.
Tag
N-terminal His Tag
Mol. Weight
39.2 kDa
Reconstitution
Centrifuge the vial before opening, reconstitute in sterile 10 mM Hepes, 0.1 mM EDTA, 1 mM DTT, and 0.5 mg/mL BSA(pH 7.5) to a concentration of 0.1-1 mg/ml by gently pipetting 2-3 times, don't vortex.
Storage
The lyophilized protein is stable at -20 °C for up to 1 year. For extended storage, it is recommended to further dilute in working aliquots after reconstitution. The protein solution is stable at ≤ -20°C for 3 months, or 2-7 days at 2-8 °C under sterile conditions.Avoid repeated freeze/thaw cycle.

Ordering & Delivery
How do I place an order?
Use the Inquiry button on this page or write to tekintolga89@gmail.com. Include the catalogue number and the quantity you need.
What is the dispatch time?
In-stock items are dispatched within 1-3 business days. Items that need to be produced take longer; we confirm the date when you order.
Do you ship outside Türkiye?
Shipping is arranged case by case. Contact us with the destination and we will quote carriage and lead time.
Storage & Handling
How should an unopened kit be stored?
At 2-8 °C unless the datasheet says otherwise. Do not freeze a kit that is not marked for freezing.
How long is an opened kit stable?
It depends on the component. The Kit Components table on this page lists the storage condition for each item after opening.
What should I do if the shipment arrives warm?
Photograph the package and contact us the same day. Do not use the kit until we have confirmed it is still within specification.
Assay Questions
Which sample types can I use?
The Sample Type row in the specifications above lists the validated matrices for this product. Other matrices need validation on your side.
My background is too high. What should I check?
The usual causes are insufficient washing, contaminated buffers, or too much detection antibody. Our Protocol pages cover the full troubleshooting sequence.
Can I run fewer wells than the kit provides?
Yes. Dismountable microplates let you use part of a plate and reseal the rest with the desiccant supplied.
Technical Support
Something did not work. What do you need from me?
Send the catalogue number, the lot, your protocol deviations and the raw OD values. That is usually enough to identify the cause.
Do you provide a certificate of analysis?
Yes, per lot. Ask for it with the catalogue number and lot number.
