A system for generating a model for predicting a molecular property of a variant of a molecule is provided. For each of a plurality of variants of the molecule, the system for each structural feature, aggregates the values for the structural features of the residues of the molecule that were modified to form the variant to form a feature vector for the variant. The system assigns the value for the molecular property of the variant to the feature vector wherein the feature vector and the assigned value form training data. The system then generates the model for predicting a value for the molecular property using the training data for the plurality of variants.

Provided herein are compositions, methods and systems relating to libraries of polynucleotides such that the libraries allow for accurate and efficient hybridization after binding to target sequences. Further provided herein are probes, blockers, additives, buffers, and methods that result in improved hybridization. Such compositions and methods are useful for improvement of Next Generation Sequencing applications, such as reducing off-target binding or reducing workflow times.

The present invention provides a novel method for identifying a molecular structure by single crystal X-ray analysis. A single crystal that gives an X-ray diffraction spectrum sufficient for determining the structure of the molecule can be efficiently obtained by including a test molecule in a metal complex and then crystallizing the test-molecule-including metal complex. By analyzing this single crystal by X-ray analysis, it is possible to determine the structure of the test molecule without obtaining a single crystal of the test molecule. With the method according to the present invention, the structure of a test molecule in a trace amount of sample can also be determined.

Present disclosure provides a method including isolating DNA from a source, thereby providing a composition including the isolated DNA. The isolated DNA has at least first and second target regions, where the length of the second target region is greater than the length of the first target region. The method further includes quantifying a total mass of the isolated DNA, quantifying a first quantification cycle (C.sub.q) of the first target region and a second C.sub.q of the second target region, and calculating a Q-ratio for the isolated DNA by dividing the second C.sub.q by the first C.sub.q. The method further includes determining a value for a quality-mass constant (k.sub.Qm), estimating a required input mass by dividing k.sub.Qm by the Q-ratio, and preparing the isolated DNA for sequencing if the total mass of the isolated DNA in the composition is equal or greater than the required input mass.

A modified peptide or a modified polypeptide has the amino acid sequence of Thr-Val-Asp-Ser-Cys-Leu-Thr (SEQ ID NO: 1) and adhesiveness to a norbornene-based polymer. A ratio of the total number of amino acids constituting the modified peptide or the modified polypeptide to the number of oligopeptides consisting of the amino acid sequence of SEQ ID NO: 1 contained in the modified peptide or the modified polypeptide is 7 or more and 80 or less. The number of oligopeptides consisting of the amino acid sequence of SEQ ID NO: 1 is 1.
