Storage & handling

Lyophilized material: Store at -20°C in a tightly sealed vial, protected from light and moisture. Allow the sealed vial to reach room temperature before opening.
After reconstitution: For short-term laboratory handling, keep at 2-8°C. For longer storage, aliquot and freeze at <=-20°C when the experimental buffer is compatible. Avoid repeated freeze-thaw cycles.

WHOLESALE SOURCING

Review the BT10 batch record together with its source-field discrepancy.

Yili lists BT5 and BT10. The BT10 COA identifies batch BT202638. Its source PDF lists molecular weight 899.01 while the referenced chemical identity uses 889.01, so that field requires issuer confirmation.

State BT5 or BT10 and the required kits. Do not use the BT10 result for BT5, another batch, BB blends or KLOW without matching identifiers.

01
Select BT5 or BT10
Keep the standalone TB-500 presentation separate from blends that contain a TB-500-labelled component.
02
Read the complete source note
Compare the sample, batch and analytical results, and ask the issuer to resolve the molecular-weight field before relying on it.
03
Request an order-specific answer
Add quantity, destination, packaging and the current document required for the proposed material.

Request a specification-led quote.

Include the code, quantity, destination and batch or document number you want to review.
