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, 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.

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.

Target Background

Function

The IFNLR1/IL10RB dimer is a receptor for the cytokine ligands IFNL2 and IFNL3 and mediates their antiviral activity. The ligand/receptor complex stimulate the activation of the JAK/STAT signaling pathway leading to the expression of IFN-stimulated genes (ISG), which contribute to the antiviral state. Determines the cell type specificity of the lambda interferon action. Shows a more restricted pattern of expression in the epithelial tissues thereby limiting responses to lambda interferons primarily to epithelial cells of the respiratory, gastrointestinal, and reproductive tracts. Seems not to be essential for early virus-activated host defense in vaginal infection, but plays an important role in Toll-like receptor (TLR)-induced antiviral defense. Plays a significant role in the antiviral immune defense in the intestinal epithelium.

IFN-lambda4 suppressed HIV infection of macrophages. This IFN-lambda4-mediated HIV inhibition was compromised by the antibodies against IFN-lambda receptor complex, IFN-lambdaR1/IL-10R2. PMID: 30247785
Significant associations were observed for 4 variants in IFNAR2, IFNLR1 with hepatitis B virus infection, and IFNLR1-rs4649203 was associated with hepatitis B recovery. Moreover, the authors demonstrated the clear relevance of 5 polymorphisms in IFNA1, IFNA2, IFNL4 with hepatocellular carcinoma. PMID: 29080269
In this structure, the receptor peptide forms an 85-A-long extended chain, in which both the previously identified box1 and box2 regions bind simultaneously to the FERM and SH2-like domains of JAK1. PMID: 27725180
Results show that IFNLR1 box1 and box2 motifs are required for stable complex formation with JAK1 and the crystal structure of JAK1 reveals IFNLR1 box1 binding site in the FERM domain. Also, structure-based mutagenesis reveals IFNLR1 PxxLxF motif that is essential for binding. Structure of JAK1 with IL10RA box1 indicates conservation among class II receptors. PMID: 27133025
Selective expression of IFNlambdaR1 was considered to be a plus point towards the targeted anti-viral activity of IFNlambdas but artificial control on its expression will surely make IFNlambdas a better drug with enhanced activity. PMID: 27166550
expression of IL-28RA mRNA may be correlated with the pathogenesis of systemic lupus erythematosus PMID: 25911176
Polymorphism within the IL-28R1, but not in IL-28B, is associated with benign prostatic hyperplasia and lower urinary tract symptoms in Chinese. PMID: 26400298
Results show that the distribution of IL10RB and IL28RA genotypes among the Hepatitis C virus-infected and control groups did not differ significantly. PMID: 24144988
This study is the first to show the activation of a type III interferon response in low-risk human papillomavirus positive cervical cells and suggests that the lack of this response may be related to lesion progression. PMID: 24510368
IL28RA polymorphism (rs10903035) seems to be implicated in the glucose homeostasis because AA genotype increases the likelihood of IR, but this association was different depending on hepatic fibrosis and HCV genotype. PMID: 24438680
Epigenetic reprogramming of IFNLR1-mediated response potentiates antiviral activity and suppresses tumor growth. PMID: 24409098
IFN-lambda receptor 1 expression is induced in chronic hepatitis C and correlates with the IFN-lambda3 genotype and with nonresponsiveness to IFN-alpha therapies. PMID: 24752298
The rs12980275 AG/GG genotype and rs10903035 G allele remained independently associated with early pegylated interferon and ribavirin failure of hepatitis C in hepatitis C/HIV coinfected patients. PMID: 23565619
Plasmacytoid dendritic cells are major producers of IFN-lambda2 (a type III interferon) in response to viral stimulation and also express functional receptors for this cytokine. PMID: 22891284
No consistent association is found between IL28RA and multiple sclerosis in a Basque-Spanish population. PMID: 22386267
two SNPs in IL28RA are correlated with susceptibility to HCV infection and spontaneous viral clearance, which implicates a primary role of IL28RA in the outcomes of HCV infection PMID: 21742059
IFN-lambdaR1 consists of two distinct domains having fibronectin type III topology. PMID: 20934432
Although the IFN-lambda1(Bac)-IFN-lambda1R1 and IFN-lambda1(Ins)-IFN-lambda1R1 complexes differed only in the nature of the expression system used for the ligand, their crystallization conditions and crystal forms were quite different PMID: 20057073
study supports that IFN-lambdas do not influence every type of cell and that membrane-associated variant IFN-lambda R1 expression is not sufficient to ensure cellular sensitivity toward these cytokines. PMID: 19798076
IL-28 and IL-29 interact with a heterodimeric class II cytokine receptor that consisted of IL-10 receptor beta (IL-10Rbeta) and an orphan class II receptor chain, designated IL-28Ralpha. PMID: 12469119
distinct receptor complex that is utilized by all three IFN-lambda proteins for signaling and is composed of two subunits, a receptor designated CRF2-12 (also designated as IFN-lambdaR1) and a second subunit, CRF2-4 (also known as IL-10R2) PMID: 12483210
interleukin (IL)-28 receptor tyrosine residues have roles in antiviral and antiproliferative activity of IL-29/interferon-lambda 1 PMID: 15166220
