Anti-Mouse CXCR4 Antibody (Cx4Mab-1)	CXCR	Cancer
Anti-Mouse CXCR4 Antibody is a monoclonal antibody that specifically recognizes murine CXCR4 (C-X-C chemokine receptor 4), also known as fusin or CD184. CXCR4 is a seven-transmembrane G protein–coupled receptor whose principal endogenous ligand is CXCL12 (stromal cell–derived factor-1α, SDF-1α) and is widely expressed in hematopoietic cells, endothelial cells, neurons, as well as embryonic and adult stem cells. The CXCR4–CXCL12 signaling axis activates multiple downstream pathways, including ERK1/2, Ras, p38 MAPK, PLC/MAPK, and SAPK/JNK, thereby regulating cell survival, proliferation, migration, and stemness maintenance. Aberrant overexpression of CXCR4 is closely associated with poor prognosis and metastasis in various cancers, with CXCR4-positive tumor cells preferentially home to CXCL12-rich tissues such as the liver, bone marrow, lung, and lymph nodes. Accordingly, CXCR4 and its CXCL12-related antagonists emerge as attractive targets for experimental anticancer therapy. Anti-Mouse CXCR4 Antibody is generated using a cell-based immunization and screening strategy and exhibits high affinity for both endogenous and exogenous murine CXCR4. Anti-Mouse CXCR4 Antibody can be used for thestudy of chronic lymphocytic leukemia and multiple myeloma .

Protein Tyrosine Kinase Compound Library

1,578 compounds

Protein tyrosine kinases (PTKs) are key signaling molecules and important drug targets. Two classes of PTKs are present in cells: the transmembrane receptor PTKs (RTKs) and the nonreceptor PTKs. The RTK family includes the receptors for insulin and for many growth factors, such as EGFR, FGFR, PDGFR, VEGFR, and NGFR. RTKs are transmembrane glycoproteins that are activated by the binding of their ligands, and they transduce the extracellular signal to the cytoplasm by phosphorylating tyrosine residues on the receptors themselves (autophosphorylation) and on downstream signaling proteins. Their principal functions of PTKs involve the regulation of multicellular aspects of the organism. Cell to cell signals concerning growth, differentiation, adhesion, motility, and death are frequently transmitted through tyrosine kinases. In humans, tyrosine kinases have been demonstrated to play significant roles in the development of many disease states, including diabetes and cancers.

MCE designs a unique collection of 1,578 compounds that act as a useful tool for PTKs-related drug screening and disease research.

3D Diverse Fragment Library

5,278 compounds

Fragment-based drug discovery (FBDD) is well suited for discovering both drug leads and chemical probes of protein function. 3-dimensionality (3D) diversity is pivotal because the molecular shape is one of the most important factors in molecular recognition by a biomolecule. There is a developing appreciation that 3D fragments could offer opportunities that are not provided by 2D fragments.

MCE 3D Diverse Fragment Library consists of 5,400 non-flat fragment-like molecules (average Fsp3 value 0.58). More than 4,700 fragment compounds contain at least one chiral center in the structure. The key concepts that underlie the library design were 3D shape, structural diversity, reactive functionality and fragment-like. This 3D Diverse Fragment Library brings higher fragment hit optimization and increases the likelihood to find innovative hits in FBDD.

HY-L942

Allosteric Modulator Fragment Library

1802 compounds

In contrast to the high conservation of conventional orthosteric sites, allosteric sites possess structural characteristics of low conservation, high hydrophobicity, weak polarity, confined spatial geometry, and dynamic cryptic properties. There is a significant difference between their core structures and orthosteric pockets — allosteric pockets are mostly dynamic grooves formed by protein conformational changes, subunit interface clefts, or shallow depressions, rather than the rigid "keyhole" structure of orthosteric sites. With looser spatial constraints, allosteric sites have the advantages of high selectivity and low off-target risk, and have become an important direction in new drug discovery.

Based on the dynamic, hydrophobic, and narrow-long spatial characteristics of allosteric pockets, MCE has performed targeted modification and screening of fragments. The screening criteria strictly conform to the requirements of allosteric binding: molecular weight is controlled at 120–280 Da (to meet the core needs of small molecules in fragment libraries and high derivatization), hydrogen bond donors (HBD ≤ 2), hydrogen bond acceptors (HBA ≤ 3), polar surface area (PSA = 30–80 Å²), rotatable bonds (≤ 2), moderate hydrophobicity (cLogP = 1–3.5), no strongly ionizable groups, and both appropriate rigidity and conformational flexibility to adapt to the dynamic changes of the pocket. Meanwhile, combined with the results of principal moment of inertia (PMI) analysis, fragments with high 3D diversity were obtained. Such fragments have good shape complementarity with allosteric pockets, ensuring that the fragments can smoothly enter the allosteric pockets and form stable binding, while providing room for subsequent optimization and derivation.

This library contains 1,800 structurally diverse fragment molecules with excellent drug-like properties, suitable for allosteric drug development and the design and optimization of allosteric sites. It combines the

Anti-Mouse CXCR4 Antibody (Cx4Mab-1)	CXCR	Cancer
Anti-Mouse CXCR4 Antibody is a monoclonal antibody that specifically recognizes murine CXCR4 (C-X-C chemokine receptor 4), also known as fusin or CD184. CXCR4 is a seven-transmembrane G protein–coupled receptor whose principal endogenous ligand is CXCL12 (stromal cell–derived factor-1α, SDF-1α) and is widely expressed in hematopoietic cells, endothelial cells, neurons, as well as embryonic and adult stem cells. The CXCR4–CXCL12 signaling axis activates multiple downstream pathways, including ERK1/2, Ras, p38 MAPK, PLC/MAPK, and SAPK/JNK, thereby regulating cell survival, proliferation, migration, and stemness maintenance. Aberrant overexpression of CXCR4 is closely associated with poor prognosis and metastasis in various cancers, with CXCR4-positive tumor cells preferentially home to CXCL12-rich tissues such as the liver, bone marrow, lung, and lymph nodes. Accordingly, CXCR4 and its CXCL12-related antagonists emerge as attractive targets for experimental anticancer therapy. Anti-Mouse CXCR4 Antibody is generated using a cell-based immunization and screening strategy and exhibits high affinity for both endogenous and exogenous murine CXCR4. Anti-Mouse CXCR4 Antibody can be used for thestudy of chronic lymphocytic leukemia and multiple myeloma .

Human TLR5 mRNA		mRNA
Human TLR5 mRNA encodes the human toll like receptor 5 (TLR5) protein, a member of the Toll-like receptor (TLR) family which plays a fundamental role in pathogen recognition and activation of innate immunity. TLR5 recognizes bacterial flagellin, the principal component of bacterial flagella and a virulence factor. The activation of this receptor mobilizes the nuclear factor NF-kappaB, which in turn activates a host of inflammatory-related target genes.
