29 Life Sciences New Omicron Reactive Antibodies


Most of us are aware that the Omicron variant of the SARS-CoV-2 virus possesses multiple mutations in the Spike protein. However, this variant also has mutations in the nucleocapsid protein (N) as well.


This is critically important since current antigen tests detect the nucleocapsid by immunoassay. The antibodies employed in these tests must recognise the mutated N antigen otherwise a false negative test will result.


Leading infectious disease antigens and antibodies manufacturer, ViroStat, has validated their 4 best monoclonal antibody pairs (products #3865-#3868) for reactivity with the nucleocapsid of the Omicron variant. These high affinity antibody pairs are used successfully in lateral flow and ELISA applications for antigen detection of the other variants as well.

Mixer Mill for Biological Applications and Cell Disruption


Mixer mills are widely used for homogenising biological samples such as tissue, liver, muscle, plants, corn or sputum. For cell disruption via bead beating mixer mills are also the perfect solution.


Retsch’s new Mixer Mill MM 500 vario is a versatile bench-top unit which provides ultimate performance with maximum flexibility for sample homogenisation. It accommodates adapters for different single-use vials of 0.2 ml/1.5 ml/2 ml/5 ml.


Depending on the tube and the type of adapter, 5-10 tubes can be inserted per adapter, resulting in the following maximum vial capacity per batch: 50 x 1.5 or 2 ml (or 60 x 0.2 ml) or 20 x 5 ml.


Typical grinding/homogenising processes of biological materials take less than 2 minutes. Cell disruption with a good reproducibility and efficiency takes 20 sec to 5 min, depending on the cell type. Cryogenic grinding in single-use vials can also be a suitable way to pulverise tough or temperature-sensitive samples in the MM 500 vario.

Integra Biosciences has created the D-ONE single channel pipetting module for hands-free transfers from individual tubes or wells using the ASSIST PLUS pipetting robot. This system effectively automates tedious tasks such as serial dilutions, sample normalisation, hit picking or pipetting of complex plate layouts, increasing productivity and reproducibility in the lab while reducing hands-on time, processing errors and physical strain.


The D-ONE is available in two volume ranges - from 0.5 to 300 µl and 5 to 1250 µl - to ensure optimal pipetting performance across a wide volume range. Each D-ONE module has two separate pipetting channels, using 12.5 and 300 µl or 125 and 1250 µl GripTips for high and low volumes respectively. The D-ONE pipetting module senses the liquid level immediately before aspiration, and is compatible with all Integra GripTips used for benchtop pipetting devices. This avoids the need for special tips, and saves time during program set-up. Combined with a specially designed D-ONE tip deck that can accommodate two tip racks, this allows the ASSIST PLUS to automatically switch between the different GripTips without tedious manual intervention, offering longer walk-away times.


The combination of the D-ONE and ASSIST PLUS ensures accurate and reproducible results every time by successfully automating dilution calculations for normalisations, hit picking without any transcription errors, and master mix preparations for varying sample numbers and volumes. This makes the D-ONE the perfect add-on for labs that want to go beyond the possibilities of multichannel pipetting to access unlimited applications on the ASSIST PLUS.
