Recombinant Human IL-4

Interleukin-4 (IL-4) is a pleiotropic cytokine that induces differentiation of naive helper T cells (Th0 cells) to Th2 cells and produced by mast cells, activated T cells and bone marrow stromal cells. It has many biological roles, including the stimulation of activated B-cell and T-cell proliferation, and the differentiation of CD4+ T-cells into Th2 cells. It enhances both secretion and cell surface expression of IgE and IgG1 and also regulates the expression of the low affinity Fc receptor for IgE (CD23) on both lymphocytes and monocytes. The human IL-4 has a compact, globular fold, stabilised by 3 disulphide bonds. The human IL-4 shares about 40%a.a. sequence identity with mouse/rat IL-4 and they are species-specific in their activities.

$223.00 - $7,096.00

Recombinant Human IL-3

Interleukin-3 (IL-3) is a cytokine encoded by the IL-3 gene on chromosome 5. It is primarily produced by activated T cells, as well as human thymic epithelial cells, activated murine mast cells, keratinocytes, and neurons/astrocytes. IL-3 plays a key role in hematopoiesis by regulating the production, differentiation, and function of granulocytes and monocyte-macrophage lineages. Human IL-3 is a monomeric, non-glycosylated polypeptide consisting of 133 amino acid residues. Due to low sequence homology, human IL-3 does not exhibit activity on murine cells.

$560.00 - $8,515.00

Recombinant Human IL-2

IL-2 is a potent immunoregulatory lymphokine produced by T cells in response to antigenic or mitogenic stimulation. It is expressed by CD4⁺ and CD8⁺ T cells, γδ T cells, B cells, dendritic cells, and eosinophils. IL-2/IL-2R signaling is essential for T-cell proliferation and other key immune functions. The IL-2 receptor consists of three subunits: 55 kDa IL-2Rα, 75 kDa IL-2Rβ, and 64 kDa common gamma chain (γc/IL-2Rγ), which exist in various preformed complexes on the cell surface. Mature human IL-2 shares 56% and 66% amino acid sequence identity with mouse and rat IL-2, respectively. Human and mouse IL-2 exhibit cross-species activity.

$225.00 - $1,745.00

Recombinant Human IL-1 RA

Interleukin-1 receptor antagonist (IL-1RA) is a member of the IL-1 family. It is secreted by various cell types, including immune cells, epithelial cells, and adipocytes, and acts as a natural inhibitor of the pro-inflammatory effects of IL-1β. IL-1RA inhibits the activity of both IL-1α and IL-1β, modulating a range of IL-1–related immune and inflammatory responses. Cytokines such as IL-4 and IL-13 can amplify IL-1β–induced production of both soluble and intracellular forms of IL-1RA. In synovial fibroblasts, IL-1RA synthesis is significantly upregulated by IL-1, TNF-α, or PDGF. The protein shares 26% amino acid sequence homology with IL-1β and 19% with IL-1α.

$755.00 - $1,330.00

Recombinant Human IL-1β

Interleukin-1 beta (IL-1β) is a non-secreted proinflammatory cytokine primarily produced by activated macrophages, as well as neutrophils, epithelial cells, and endothelial cells. It plays a central role in regulating immune responses and exhibits metabolic, physiological, and hematopoietic activities. IL-1β and IL-1α bind to the same receptor and share similar—but not identical—biological properties. The mature human IL-1β shares 96% amino acid sequence identity with rhesus IL-1β, and 67%–78% identity with canine, mouse, and rat IL-1β.

$560.00 - $8,515.00

Recombinant Human IL-1α

Interleukin-1 alpha (IL-1α) is a non-secreted proinflammatory cytokine primarily produced by activated macrophages, as well as neutrophils, epithelial cells, and endothelial cells. It plays a central role in immune regulation and exhibits metabolic, physiological, and hematopoietic functions. IL-1α and IL-1β bind to the same receptor and share similar biological properties. The mature IL-1α sequence is 60–70% conserved across species, and human IL-1α is biologically active on murine cell lines. Recently, IL-1α has also been applied in cosmetic and dermatological formulations to support dermal structure and function.

5× DualHS G3mTTx qPCR Mix (Lyo-Ready)

5× DualHS G3mTTx qPCR Mix is a specialized 5× master mix for TaqMan-based Real-Time PCR, featuring dual aptamer-based HotStart enzymes—G3Taq DNA Polymerase and Extreme ThermoStable Reverse Transcriptase (ET RTase)—along with dNTPs, Mg²⁺ activator, Mg²⁺ ions, and stabilizers. The mix enables bias-free amplification of both DNA and RNA under Mg²⁺-dependent conditions (no Mn²⁺ required) and supports ultrasensitive detection of nucleic acids.

$300.00 - $1,200.00

AP HS-G3Taq DNA Polymerase (Glycerol Free)

G3Taq DNA Polymerase is a third-generation DNA polymerase featuring 5'→3' exonuclease activity and lacking 3'→5' exonuclease (proofreading) activity. It exhibits exceptional tolerance to common inhibitors such as ethanol, guanidine salts, and heparin, making it highly effective even with low-purity DNA templates. AP HS-G3Taq DNA Polymerase employs a high-affinity nucleic acid aptamer to reversibly block the enzyme’s active site. At low temperatures (<37°C), the polymerase remains mostly inactive (activity <10%). As the temperature increases beyond 50°C, the aptamer dissociates from the active site, thereby reactivating the enzyme.

CM HS-G3Taq DNA Polymerase is a chemically modified HotStart version of the enzyme. It remains completely inactive below 50°C and regains full activity only after heating at 95°C for 5 minutes. This feature effectively suppresses nonspecific amplification and significantly enhances PCR specificity and sensitivity.
