Chromatrap® Your Chromatin!


We are pleased to present you with Chromatrap®*, a revolutionary solid-state platform from the UK that enables more efficient, sensitive and robust chromatin immunoprecipitation (ChIP).

Compared to current methods, the following are what makes Chromatrap® superior:

Unlike bead-based ChIP, Chromatrap eliminates common manual handling problems and the need for time-consuming blocking steps to reduce non-specific binding. In under 5 hours from chromatin loading to qPCR or sequencing, Chromatrap significantly reduces the assay time for ChIP, enabling more samples to be analysed increasing laboratory throughput and efficiency.

  • Highly sensitive – Perfect for low abundant proteins and transcription factors
  • Low background – No pre-blocking required
  • Reduced IP times – ChIP in under 5hrs
  • Less manual handling – Reduced errors and sample loss
  • Wide dynamic range – ChIP from as little as 1000 cells
  • High throughput capability – Test multiple samples, antibodies and gene targets
  • Cost-efficient solution – Save precious antibody

How does Chromatrap perform in the laboratory?

  • Target enrichment typically 6x greater with Chromatrap
  • Target enrichment typically 15-20x greater with Chromatrap
  • Best signal-to-noise of any kit at low chromatin loadings
  • 2-3x higher signal-to-noise than bead-based methods
  • Less non-specific binding
  • Shorter protocol, higher chromatin yields
  • Wider dynamic range: 500ng - 50μg chromatin
  • Less manual handling & increased binding capacity within column
  • No DNA clean up required for qPCR
  • Perform several ChIP assays from a single sample

About Chromatrap®: Porvair Sciences is part of Porvair plc, a specialist filtration company listed on the London Stock Exchange. They are one of the largest manufacturers of Ultra-Clean microplates, 96-Well Filter Plates and Microplate handling equipment for life science and synthetic chemistry, with over 25 years of experience in microplate manufacturing.

The potential of the patented filter used in Chromatrap® was first noticed by academics at Essex University and later developed in collaboration with Swansea University’s medical school.

In an academic/industrial partnership, the product range was developed to offer a faster, more sensitive method of chromatin immunoprecipitation. From an initial kit designed for PCR analysis, the technology has been developed into a full product range, particularly suited to small or low abundant biological samples.

The range is manufactured in Porvair’s bioscience facilities in North Wales and sold globally.

Complete Solutions for COVID-19 Diagnostics


Diagnostic testing for the new coronavirus strain COVID-19 can be carried out through molecular analysis or by ELISA.

The main advantages of RT-qPCR are the speed, sensitivity and ability to detect transmission of the disease very early on in the course of infection. However, since antibodies continue to circulate after an infection has cleared, serology tests are useful tools for monitoring the evolution of an outbreak and for identifying previously undiagnosed infections in the asymptomatic population.

Meridian offers a range of COVID-19 testing solutions for both molecular and immunoassay technologies. From optimized RT-qPCR mixes ideal for fast and accurate molecular testing through to high performing recombinant antigens for IgG and/or Igm testing, we have your needs covered.

Fetal Bovine sera


US Origin Fetal Bovine Serum (FBS) is the most widely used FBS in the world. Although US Origin FBS is considered the world’s standard for quality it is never the less becoming a lower standard in the view of the OIE (World Organization for Animal Health) and other regulatory bodies. On a scale of 1-4 for geographical BSE risk (GBR), with 1 being the lowest risk and 4 being the highest risk, US FBS ranks a 3 – demonstrating a moderate to high risk that BSE exists in the USA. US Origin FBS provided by J R Scientific is of the highest quality available in the USA. It is collected using state of the art aseptic collection techniques resulting in low endotoxin and hemoglobin concentrations.
