Herein is reported a method for selecting a full length antibody comprising the steps of a) generating from a parent full length antibody a plurality of full length antibodies by randomizing one or more amino acid residues selected from the amino acid residues at positions 1-23 in the heavy chain variable domain (numbering according to Kabat), at positions 55-83 in the light chain variable domain (numbering according to Kabat), at positions 145-174 in the first heavy chain constant domain (numbering according to EU index) and at positions 180- 97 in the first heavy chain constant domain (numbering according to EU index), b) determining the binding strength of each of the full length antibodies from the 10 plurality of antibodies to the human neonatal Fc receptor (FcRn), and c) selecting a full length antibody from the plurality of full length antibodies that has a different binding strength to the FcRn than the parent full length antibody.

The invention provides for a cartridge (300) for an automatic analyzer (1100), wherein the cartridge is operable for being spun around a rotational axis (102). The cartridge comprises: a fluid chamber (104) for receiving a fluid (307), an aliquoting chamber (108), a first duct (106) connecting the fluid chamber and the aliquoting chamber, a metering chamber (112) operable for causing fluid to fill the metering chamber using capillary action, a second duct (110) connecting the metering chamber with the aliquoting chamber, and a vent (128). The vent is connected to the metering chamber. The vent is nearer to the rotational axis than the metering chamber. The metering chamber has side walls (204) and a central region (206). The side walls taper away from the central region, wherein capillary action next to the side walls of the metering chamber is greater than in the central region of the metering chamber. The second duct comprises a duct entrance (114) in the aliquoting chamber. The second duct further comprises a duct exit (116) in the metering chamber wherein the duct exit is closer to the rotational axis than the duct entrance. The second duct is operable for causing fluid to flow to the metering chamber using capillary action. The cartridge further comprises a downstream fluidic element (122) connected to the metering chamber via a valve (121) and a fluidic structure (336) for processing a biological sample into the processed biological sample. The fluidic structure comprises a measurement structure (344, 1110) for enabling measurement of the processed biological sample, wherein the fluidic structure is configured for receiving the biological sample.

Handheld analyte meters are provided that have a measurement module, a rechargeable battery and a charging control to select a maximum charging current to regulate self-heating during recharging that can interfere with analyte tests. Prior to beginning a charging session, the charging control selects the maximum charging current that does not change during the charging session based capacity of a charging source along with a first temperature measured near the battery that is compared with a first temperature range. By selecting the maximum charging current in this manner, the risk of the measurement module preventing a test under high lock-out conditions and the risk of the measurement module allowing a test when low lock-out conditions that are masked is reduced. Methods also are provided for using/operating such devices.

The molecular diversification of cell surface molecules has long been postulated to impart specific surface identities on neuronal cell types. The existence of unique cell surface identities would allow neurons to distinguish one another and connect with their appropriate target cells. Although progress has been made in identifying cell type-specific surface molecule repertoires and in characterizing their extracellular interactions, determining how this molecular diversity contributes to the precise wiring of neural circuitry has proven challenging. Here, we review the role of the cadherin, neurexin, immunoglobulin and leucine-rich repeat protein superfamilies in the specification of connectivity. The emerging evidence suggests that the concerted actions of these proteins may critically contribute to the assembly of neural circuits. © 2016 Macmillan Publishers Limited. All rights reserved.
