3. What applications has this product been tested in ELISA? Immune colloidal gold and Immunochromatography? If yes, can you please provide QC data for you current lot.
Answer: This product has been tested in ELISA (Serum titer and competition tests during immunization) but hasn't been tested in Immune colloidal gold and Immunochromatography.
This product can be applied in Immune colloidal gold and Immunochromatography in theory, but we haven't validated yet. Here attached is the QC data of ELISA.

Q:

Can you please tell me the country of origin of the Bovine Serum Albumin for product CSB-MC00281a0105.

A:
Very nice to receive your inquiry. The country of origin of the Bovine Serum Albumin is United States.
Q:

We want to purchase ~40 vials of this material, or purchase regularly over 6 years. Do you know if this product would survive a ~6 year storage?
If the 6-year storage is fine, could you please advise on pricing for 30-40 vials?
If the 6-year storage is unlikely, can you venture a guess as to whether or not you will still be providing this item in 6 years?

A:
Very nice to receive your inquiry.
1. The quality and titer of this product are quite good. We could provide a stable and long-term supply for this product.
2. Currently we have 15mg-20mg of stock for this product, so can't provide all 30-40mg from same lot. However, even if we have 30-40mg of stock, it is impossible to store the current lot for six years.
We will ensure the same production process, the consistent product parameters, and control the difference between different lots. Please confirm whether you could accept different lots.
If you are concerned about lot difference, we could produce a new lot within 10 business days and send the old lot and new lot to you together, you could evaluate the different lots.
3. The expected shelf life of this product is 2-3 years, in Lyophilized Powder, stored at -20℃. We don't suggest you to purchase 30-40mg at one time, instead, we suggest you to purchase this product regularly over 6 years. You could determine the purchase interval yourselves, for example, you could purchase 5-7mg at once time every year, or purchase monthly.
Please remark "This order is from the old customer who is conducting a six-year project."
