Form Liquid or Lyophilized powder
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.
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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
and FAQs
Protein FAQs
Storage Condition Store at -20°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.

Q&A and Customer Reviews


Regarding CSB-EP021062HU -Corticosteroid Binding Globulin , Does the method you use in protein purification involves the use of cortisol (or other related compound that may be bound to the recombinant CBG)?
We are planning to do experiments on cortisol binding, I would like to confirm that the recombinant CBG you have contains or does not contain bound cortisol.

Very nice to receive your inquiry. This is a ready-to-ship protein. The product details are as below.
Lead Time: 3-5 working days
Expression Region: 23-405aa, full length
Tag Info: N-terminal GST-tag
Target Protein Sequence:


We use nickel column affinity purification method to purify this protein. There contains NO Cortisol in the storage buffer.

The GST tag is not listed in this sequence below, so I want to know if the N terminal GST tag is intact in the final protein that is delivered to us or is it cleaved or removed during the final purification step. The expression Region: 23-405 with N terminal GST tag; AA Sequence:


Very nice to receive your inquiry. CSB-EP021062HU is tagged with N-terminal GST-tag. The AA sequence refers to the target protein sequence. The complete sequence is as below.


Note: The sequence in front of "+" is the GST-tag sequence, and the sequence behind of "+" is the target protein sequence.
