The present invention relates to a conjugate of cell penetrating peptide and an active ingredient; and its use. Specifically, a conjugate including a cell penetrating peptide which is a peptide comprising any one amino acid sequence of SEQ ID NO: 1 to SEQ ID NO: 156, a fragment of any one sequence of SEQ ID NO: 1 to SEQ ID NO: 156, or a peptide having above 80% homology with the above-mentioned sequence; and a composition comprising the same are disclosed.

Methods, systems, compositions and kits are provided for the analysis of target molecules using chromophoric polymer dots conjugated to biomolecules. The use of chromophoric polymer dots improves detection sensitivity and stability when compared with existing techniques. In some aspects, methods, systems, and kits are provided for detecting a target protein using chromophoric polymer dots conjugated to biomolecules in a Western blot analysis. Related methods, systems, compositions and kits are also provided.

The present invention relates to the use of a control marker for implementing analysis methods on spots, in particular in the context of multiplex analyses. The present invention thus relates to solid supports containing said control marker, their preparation method and their use in analysis methods. The present invention makes it possible to verify the presence, location and/or integrity of the spots at the end of the analysis method, and thus to secure the obtained results while guaranteeing that the yielded result indeed results from a present, intact and localized spot.

The present disclosure provides method of detecting senescent cells in a cell sample and methods of treating a disease, disorder, or condition associated with senescence in a subject by administering at least one senolytic agent to the subject.

Provided are dyes and compositions which are useful in a number of applications, such as the detection and monitoring protein aggregation, kinetic studies of protein aggregation, neurofibrillary plaques analysis, evaluation of protein formulation stability, and analysis of molecular chaperone activity.

A sensor for detecting an analyte can include a photoluminescent nanostructure embedded in a sensor hydrogel. The sensor hydrogel can be supported by a substrate hydrogel.

Assay modules, preferably assay cartridges, are described as are reader apparatuses which may be used to control aspects of module operation. The modules preferably comprise a detection chamber with integrated electrodes that may be used for carrying out electrode induced luminescence measurements. Methods are described for immobilizing assay reagents in a controlled fashion on these electrodes and other surfaces. Assay modules and cartridges are also described that have a detection chamber, preferably having integrated electrodes, and other fluidic components which may include sample chambers, waste chambers, conduits, vents, bubble traps, reagent chambers, dry reagent pill zones and the like. In certain preferred embodiments, these modules are adapted to receive and analyze a sample collected on an applicator stick.

Specifically, a conjugate including a cell penetrating peptide which is a peptide comprising any one amino acid sequence of SEQ ID NO: 1 to SEQ ID NO: 156, a fragment of any one sequence of SEQ ID NO: 1 to SEQ ID NO: 156, or a peptide having above 80% homology with the above-mentioned sequence; and a composition comprising the same are disclosed.

A method detects a target material in a sample, and includes: providing an aptasensor having a first aptamer capable of binding with hemin; a second aptamer capable of binding with the target material; and a nucleotide linker connecting the first aptamer and the second aptamer, adding hemin to the sample, contacting the aptasensor with the sample including hemin to bind the first aptamer with hemin and the second aptamer with the target material; adding a substrate for 1,1-oxalyldiimidazole (ODI) chemiluminescence (CL), and measuring intensity of CL.

The invention relates to improved electrochemiluminescence assay methods for phosphorylated peptides or proteins employing phospho-specific antibodies and buffer compositions that are substantially free of inorganic phosphate.
