Special offers
Vector’s unique HRP and AP enzyme substrates offer:
- Novel colour choices - stain antigens in pigmented tissues and melanomas, or localise multiple antigens in a single tissue section
- Visibility under brightfield, darkfield, or electron microscopy
- Unique spectral profiles - useful for antigen co-localisation using spectral imaging systems
Their relative sensitivity and compatibility when used together, are important factors to consider when choosing substrates.
25% off on purchases of minimum 2 or more substrates from Vector Laboratories.
Enzyme substrate combination chart
This enzyme substrate combination chart ensures that distinct colors are visible and of high quality after the labelling reactions are completed. + Indicates good contrast – Indicates incompatiblity of substrates for various reasons.
The offer is valid until 31.12.2023. Promotional code #BNH2-23 must be referenced when ordering to receive the discount.
Optical density measurement
Another method for bacterial quantification is optical density (OD) measurement, which measures the degree of light scattering caused by bacteria. For OD measuring, we offer the DEN-600 Photometer from Biosan which is a compact, portable, and rechargeable device able to conduct measurements at 600 nm wavelength. The device can also be used for McFarland turbidity measurements, Bradford protein assay, and other methods that can be adjusted or optimized using 600 nm wavelength.

Automated bacterial counting
The QUANTOM Tx Microbial Cell Counter from Logos Biosystems holds many advantages over other counting techniques as it is an image-based and fluorescent automated cell counter that provides fast and accurate cell counts. The counter is compatible with gram-positive, gram-negative, and viable but nonculturable (VBNC) bacteria. QUANTOM Tx even has a bacteria-specific declustering algorithm which enables counting of individual bacteria, including all varieties of shapes, sizes, and arrangements of different bacteria.
A Quantom Centrifuge is also available for spinning cell counting slides to immobilize and evenly distribute the bacteria cells throughout the counting chamber to ensure accurate results.
Available counting results include cell concentration, average size, total cell number or number of viable and non-viable cells. Cell concentration or number can even be graphed according to fluorescent object size.
