<p>Polyinosinic acid-polycytidylic acid (Poly I:C), an agonist of TLR3 toll-like receptors, is a synthetic double-stranded RNA analog, consisting of polyinosinic acid (poly I) paired with polycytidylic acid (poly C), forming a stable duplex structure. PolyI:C stimulates the secretion of pro-inflammatory cytokines and type I interferon through its interaction with endosomal Toll-like receptor 3 (TLR-3) and the cytoplasmic receptors melanoma differentiation-associated gene 5 (MDA-5) and retinoic acid-inducible gene I (RIG-I). This immunostimulant activity makes Poly I:C a useful vaccine adjuvant and is used in vaccine formulations.  Poly I:C and its stabilized analogs (e.g., poly-ICLC) are also being actively researched for their dual role in oncology: directly targeting tumors and acting as immune potentiators. For example Poly I:C can induce apoptosis in tumor cells and stimulate immunogenic cell death and is therefore being explored alongside chemotherapy, radiotherapy, and checkpoint inhibitors, helping to overcome resistance mechanisms and strengthen treatment outcomes. We can supply PolyI:C to all stages of your project - from R&amp;D and preclinical phases right up to GMP commercial manufacture.

<p>LDA is a technique for extracting spectral features from a set of spectra. It uses the probabilistic model of discriminant analysis to discriminate between groups of spectra. LDA has been shown to outperform other techniques, such as PCA and MDA, in analyzing datasets with a small number of variables. The algorithm is incrementally updated with new data points and parameters, which makes it an attractive choice for real-time applications.</p>
