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°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

3-7 business days

Notes

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

■ Q&A

Regarding the 2 mg of Human CLEC4C proteinCSB-MP855470HU that we received against PO# cusabio11Dec17/1.
We have some questions that we hope you can urgently answer:
1) We are planning some Mass Spec work, which we cannot do without the following information. This work is part of our decision on whether to order more of the same lot# of this protein.
2) The protein has a His-tag. Could you please let us know the number of histidine residues and the location of the tag (i.e. N-terminus or C-terminus)?
3) Is the His Tag on the N-terminal or the C-terminal of the protein?
4) Is there a linker between the CD303 sequences and the His-Tag? If so, please can you provide the sequence of this linker?
5) Can you send us the full sequence of the recombinant protein? The website only provides the extra-cellular domain as reported in Uniprot.

Thanks for your inquiry.
1. The tag is N-terminal 6xHis-tagged.
2. Yes, it have a linker, only 2 amino acid. That is RT.
3. The full sequence with tag is as follow:

We would like to know what mammalian cell line the protein is produced in, so we can predict the glycosylation that they expect from their mass spec.

Thanks for your inquiry. The mammalian cell we use is HEK293.

Target Background

Function

Lectin-type cell surface receptor which may play a role in antigen capturing by dendritic cells. Specifically recognizes non-sialylated galactose-terminated biantennary glycans containing the trisaccharide epitope Gal(beta1-3/4)GlcNAc(beta1-2)Man. Binds to serum IgG. Efficiently targets ligand into antigen-processing and peptide-loading compartments for presentation to T-cells. May mediate potent inhibition of induction of IFN-alpha/beta expression in plasmacytoid dendritic cells. May act as a signaling receptor that activates protein-tyrosine kinases and mobilizes intracellular calcium.
