Buffer If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 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°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
and FAQs
Protein 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 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.

Looking for a source for rat TSH standard separate from Elisa Kits.

Thanks for your inquiry,
TSH is composed of alpha and beta subunits glycoprotein, including alpha subunits in Thyroid stimulating hormone (Thyroid - stimulating hormone, TSH), human chorionic gonadotropin (human chorionic gonadotropin, hCG), luteinizing hormone, luteinizing hormone, LH) and follicle-stimulating hormone (follicle - stimulating hormone, FSH) almost the same as in the four kinds of hormone, Their difference is reflected in their subunits, which determine their receptor specificity, so they are generally reported as subunits for scientific research and diagnosis.
Therefore, we recommend the following developed price list proteins to our customers:
