Methods to assess biological enzyme activity directly in a complex clinical sample. To such a sample, e.g., plasma, an exogenous synthetic peptide substrate for an enzyme present in the sample and to be assessed is added. The sample then undergoes mass spectrometric immunoassay (MSIA) to monitor the mass spectral profile of the immuno-purified exogenous synthetic peptide substrate directly from the sample. Using the resulting profile, parameters such as enzyme activity and effect of enzyme modulators, including therapeutics administered to an individual for a condition involving the enzyme, may be determined.

An adjustable pipetter stand having a base plate and an arm extending vertically therefrom. The base plate receives a fluid vessel in a workspace defined by the base plate. A vertical guide rail, operatively coupled to the vertically extending arm, receives a guide block that is also operatively coupled to a pipetter. The guide block is configured to support a selected vertical position of the pipetter along the vertical guide rail.

A stackable pipette tip tray is described. The pipette tip tray includes a deck having first and second opposing longitudinal side edges. A plurality of shaft apertures is arranged into a plurality of longitudinal rows on the deck. Each of the shaft apertures has a first size or shape configured to receive a shaft of a pipette tip. The deck also includes a plurality of tip apertures that is also arranged into a plurality of longitudinal rows such that at least one of the longitudinal rows of tip apertures is located between an adjacent pair of longitudinal rows of shaft apertures. Each of the plurality of tip apertures has a second size or shape, different from the first size or shape, and is configured to receive a distal tip end of a pipette tip when one tray of pipette tips is stacked above another tray of pipette tips. The plurality of longitudinal rows of shaft apertures is further arranged such that an outer one of the plurality of longitudinal row of shaft apertures adjacent the first side edge of the deck is positioned closer to the first side edge than an outer one of the plurality of longitudinal row of shaft apertures adjacent the second side edge of the deck is positioned relative to the second side edge.

A pipette tip for use with a liquid handler is disclosed. The pipette tip includes a mandrel engaging portion positioned at a proximal end of the pipette tip and an elongated body extending distally from the mandrel engaging portion. The mandrel engaging portion includes an orifice at the proximal end of the pipette tip and an inner surface defining a lumen that is configured to engage a mandrel of a head of the liquid handler. The elongated body includes a proximal end portion adjacent the mandrel engaging portion, an intermediate portion, and a distal portion adjacent to an orifice at a distal end of the elongated body. The elongated body also includes an inner surface defining an interior cavity within the elongated body extending between the proximal end portion of the elongated body and the distal end. The elongated body has a wall thickness at the proximal end of the elongated body that does not exceed about 0.025 inches and a wall thickness adjacent the distal end that does not exceed about 0.01 inches. A microcolumn is positioned within the distal end portion of the elongated body.

A stackable pipette tip tray (10) is described. The pipette tip tray (10) includes a deck (14) having first and second opposing longitudinal side edges (28, 30). A plurality of shaft apertures (24) is arranged into a plurality of longitudinal rows on the deck (14). Each of the shaft apertures (24) has a first size or shape configured to receive a shaft (20) of a pipette tip (22). The deck (14) also includes a plurality of tip apertures (34) that is also arranged into a plurality of longitudinal rows such that at least one of the longitudinal rows of tip apertures (34) is located between an adjacent pair of longitudinal rows of shaft apertures (24). Each of the plurality of tip apertures (34) has a second size or shape, different from the first size or shape, and is configured to receive a distal tip end (32) of a pipette tip (22) when one tray of pipette tips (22) is stacked above another tray of pipette tips (22). The plurality of longitudinal rows of shaft apertures (24) is further arranged such that an outer one of the plurality of longitudinal rows of shaft apertures (24) adjacent the first side edge (28) of the deck (14) is positioned closer to the first side edge (28) than an outer one of the plurality of longitudinal rows of shaft apertures (24) adjacent the second side edge (30) of the deck (14) is positioned relative to the second side edge (30).
