A horseshoe crab Factor C protein having activity of Factor C, wherein the horseshoe crab is selected from Tachypleus tridentatus, Limulus polyphemus, and Carcinoscorpius rotundicauda, and wherein the horseshoe crab Factor C protein is produced through being recombinantly expressed from a Chinese Hamster Ovary (CHO) DG44 cell or HEK cell.

The present disclosure relates kits and methods for measuring the potency of an andexanet sample in neutralizing a factor Xa inhibitor and restoring the activity of a wild-type factor Xa.

A horseshoe crab Factor C protein having activity of Factor C, wherein the horseshoe crab is selected from Tachypleus tridentatus, Limulus polyphemus, and Carcinoscorpius rotundicauda, and wherein the horseshoe crab Factor C protein is produced through being recombinantly expressed from a Chinese Hamster Ovary (CHO) DG44 cell or HEK cell.

The invention relates generally to hybrid amebocyte lysate compositions (including both native and recombinant components) and their use in detecting and/or quantifying endotoxin in a sample.

A method for rapidly and highly sensitively measuring endotoxin relies on an endotoxin-measuring agent, which includes a factor C derived from Tachypleus tridentatus that does not have His-tag sequence at the C-terminus, a factor B of a horseshoe crab, and a proclotting enzyme of a horseshoe crab. Each of these proteins can be a recombinant protein obtainable by being expressed using a stably expressing cell line of an insect cell as a host.

Excessive deposition of extracellular matrix is a hallmark of Idiopathic pulmonary fibrosis (IPF), it is advantageous to target the cells and the mechanisms associated with this process. By targeting myofibroblasts (specialized contractile fibroblasts) that are key for the development of IPF with drugs conjugated with fibroblast activation protein (FAP), this technology helps minimize the production of extracellular matrix in the lungs and provides a new treatment option for patients diagnosed with IPF.

The invention relates to a method for in vitro investigating mitochondrial replication dysfunction in a biological sample removed from a subject susceptible of suffering from physiological ageing or physiopathological conditions related to physiological ageing, or physiopathological ageing or associated symptoms or conditions, in particular premature ageing or accelerated ageing, or of a progeroid syndrome, such as Cockayne syndrome (CS), or neurodegenerative disorders or symptoms thereof, in which the levels of at least one species selected in the group of: POLG1 protein, POLG1 RNA, POLG2 protein, protease(s) which have POLG as a target, in particular serine protease(s) such as HTRA3 protein, HTRA2 protein and, HTRA3 RNA or HTRA2 RNA, or any combination of these species, are investigated. The invention also relates to kits and uses thereof, therapeutic methods against progeroid-like syndromes or symptoms and screening method for identifying particular protease inhibitor(s) and/or nitroso-redox stress scavenger compound(s) having relevance for the symptoms discussed herein.

The present invention relates to a method for monitoring kinase activity or activation in a sample, the method comprises the steps of a) providing a sample comprising a kinase, b) incubating the sample with a protease to cleave the kinase provided in step a) into protease specific proteolytic peptides, c) applying phosphopeptide enrichment to the sample, d) analysing the sample obtained in step c) via liquid chromatography-mass spectrometry, and e) detecting phosphorylations of the kinase provided in step a), wherein the detection of step e) is performed only in case a proteolytic peptide associated with the activation region of the kinase is identified.
