Abstract: The present invention relates to a prosthetic knit based on at least a first yarn of biocompatible polymer material defining first and second opposite and openwork faces, and on at least a second biocompatible and heat-fusible monofilament yarn, forming barbs that protrude outwards from at least said first face and are obtained by melting loops generated by said second yarn, the chart followed for the knitting of said first and second yarns on a warp knitting machine having three guide bars B1, B2, B3 being the following, according to the ISO 11676 standard:—Bar B1: 1.0/0.1//—Bar B2: 1.0/7.7/6.6/7.78—Bar B3: 2.1/5.5/3.4/0.0// said second yarn following the chart of bar B3. The present invention also relates to a process for manufacturing such a knit.

Abstract: Method of dissociating the extracellular haemoglobin molecule of annelids, e.g. Arenicola marina, which can be used to obtain the protein chains forming the molecule. The method includes a step of bringing an extracellular haemoglobin sample from annelids, e.g. Arenicola marina, into contact with at least one dissociating agent, e.g. a mixture containing dithiothreitol (DTT) or tris(2-carboxyethyl)phosphine (TCEP) hydrochloride or beta-mercaptoethanol and a dissociation buffer for a sufficient length of time in order to separate the protein chains from one another.

Abstract: The invention relates to a method of dissociating the extracellular haemoglobin molecule of annelids, e.g. Arenicola marina, which can be used to obtain the protein chains forming said molecule. The inventive method is characterised in that it comprises a step consisting in bringing an extracellular haemoglobin sample from annelids, e.g. Arenicola marina, into contact with at least one dissociating agent, e.g. a mixture containing dithiothreitol (DTT) or tris(2-carboxyethyl)phosphine (TCEP) hydrochloride or beta-mercaptoethanol and a dissociation buffer for a sufficient length of time in order to separate the protein chains from one another.
