If the exact amino acid sequence of this recombinant protein is critical to your application, please explicitly request the full and complete sequence of this protein before ordering.

Mol. Weight

50.0 kDa

Protein Length

Full Length of Mature Protein

Tag Info

N-terminal 10xHis-tagged and C-terminal Myc-tagged

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. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.

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.

Troubleshooting 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.

Description

In e.coli cells, the generation of the recombinant Human CRLF1 protein includes integrating a DNA fragment encoding the Human CRLF1 protein (38-422aa) into a plasmid vector and transforming this vector into e.coli cells. Cells containing the plasmid are screened, cultured, and induced to yield the CRLF1 protein. A N-terminal 10xHis tag and C-terminal Myc tag is attached to the protein. Lysis of the cells facilitates the collection of the recombinant Human CRLF1 protein, which is subjected to affinity purification and then SDS-PAGE analysis and subsequent staining of the gel with Coomassie Brilliant Blue. The purity of the obtained recombinant Human CRLF1 protein is greater than 85%.

Target Background

Function

In complex with CLCF1, forms a heterodimeric neurotropic cytokine that plays a crucial role during neuronal development (Probable). May also play a regulatory role in the immune system.

From these results we conclude that one should consider a CRLF1-related disorder in early onset achalasia even if other Crisponi or cold-induced sweating syndrome type 1 (CS/CISS1) related symptoms are missing. PMID: 27976805
we show in this series of 12 patients from four families, all previously unpublished, that the homogeneity of the recently described c.983dupG (p.Ser328Argfs *2) mutation in CRLF1 was associated with a highly variable degree of severity, and that the phenotype significantly overlaps with the recently described COG6-related anhidrosis syndrome (MIM#615328 PMID: 26804344
CLF-1, based on its binding site for CLC and on two additional and independent sites for CNTFRalpha and sorLA, is a key player in CLC and CNTFRalpha signaling and turnover. PMID: 26858303
Article reports 11 novel mutations in CRLF1 expanding the mutational spectrum of CRLF1 in the Crisponi/cold-induced sweating type 1 syndrome to a total of 35 variants. PMID: 24488861
The mutation detected in CRLF1 has not been described in patients with CISS1, but in one with CS. These data seem to support the theory that CS and CISS1 are variants of the same disorder. PMID: 24008591
Data indicate that CRLF1 serves its protective role by a cell autonomous mechanism that is independent of the gp130/JAK signaling pathway. PMID: 23818941
In idiopathic pulmonary fibrosis, CLF-1 is a selective stimulus of type II alveolar epithelial cells and may potentially drive an antifibrotic response by augmenting both T-helper-1-driven and T-regulatory-cell-driven inflammatory responses in the lung. PMID: 22429962
CRLF1 mutations showed that phenotypic severity of the two disorders: Crisponi syndrome (CS) and cold-induced sweating syndrome type 1 (CISS1) mainly depends on altered kinetics of secretion of the mutated CRLF1 protein. PMID: 21326283
Our data suggest that the CRLF1/CLC complex disrupts cartilage homeostasis and promotes the progress of OA by enhancing the proliferation of chondrocytes and suppressing the production of cartilage matrix PMID: 19921088
