New Product Releases

LABSCREEN™ SINGLE ANTIGEN CLASS I SUPPLEMENT KITS WITH EXPANDED COVERAGE

LABScreen Single Antigen Supplement Kits complement our core LABScreen kits to create a comprehensive DSA monitoring panel, thereby reducing the number of assays needed to create a full patient profile.

With the release of Lot 2 of the LABScreen Single Antigen Class I Supplement Kit (LS1ASP01), we also offer something else our customers have been asking for — greater harmonization in coverage across our antibody screening product lines, including FlowPRA and LABScreen PRA. The new Class I Supplement kit now covers 54 alleles, including 20 new targets.

LABTYPE™ XR AND CWD RUO

In recent years, the number of HLA alleles listed in the IMGT/HLA Database has increased, on average, by 29% a year. As of September 2015, it contained over 14,000 alleles (Source: IPD-IMGT/HLA). The rapid growth in the number of known alleles presents a significant challenge, requiring new probes with every nomenclature update to help resolve newly identified ambiguities. As the number of probes continues to grow, it is becoming increasingly difficult to manufacture updated LABType kits. This is particularly true of the HD products, which can now include over 850 probes.

LABType XR and CWD assays are built on the 500 bead regions available exclusively on the LABScan3D™. More bead regions and extended exon coverage make it much easier to improve typing resolution. The CWD assays are designed to resolve alleles as defined by the CWD catalog. The XR assays are designed for laboratories interested in increased resolution beyond CWD.

The CWD assays are designed to resolve alleles as defined by the CWD catalog. The XR assays are designed for laboratories interested in increased resolution beyond CWD.

 

Product Availability

Lot 4 of the LABType XR and CWD HLA -A, -B, and -DRB1 RUO kits were released earlier this year and are available for sale. The HLA-C locus kit is projected to be released in May 2016.

HLA FUSION™ VERSION 3.5 AND HLA FUSION RESEARCH VERSION 3.5 NOW AVAILABLE

The HLA Fusion Version 3.5 Service Pack was released November 2015. This service pack corrects known defects and allows the importation of uTYPE reference files into the Fusion database for use with the source of ambiguity feature in LABType analysis.

HLA Fusion Research Version 3.5 Service Pack was also released in November. The new RUO software supports the import of uTYPE™ reference files and SeCore SBT data analysis and reporting.

Download the Software Release Notes to learn more about the new versions of HLA Fusion.

 

UTYPE VERSION 7.1 SERVICE PACK

Don’t forget to upgrade your uTYPE software, if you haven’t already done so. When you do, you’ll find an enhanced user interface with better navigation, clearer marking of bases – even on initial instantiation, and more accurate match reporting. Data output has also improved, with better report documentation.

Contact your One Lambda representative for a free upgrade.

 

ALLSET™+ GOLD DNA WIPE TEST

One Lambda’s DNA Wipe Test kit is designed to detect amplified products from UniTray™, AllSet+ Gold, and SeCore™ product lines which may interfere with the accurate reporting of test samples. Starting December 17, the “wet” UniTray™ DNA Wipe Test (Cat No. 789991) will change to the “dry” AllSet+ Gold format.

Questions related to the dry format DNA Wipe Test can be directed to One Lambda Technical Support.

 

 

 

Products in Development

SECORE™ SBT CLASS I EXTENDED

Our new SeCore Class I Extended kits will soon be in production. We expect this enhanced product to be available during the first half of 2016.

Our goal is to make SeCore the best Class I resolution kit available on the market. The new Class I sequencing kits contain additional sequencing primers for A Locus (exons 1 and 5), B Locus (exons 1 and 5) and C Locus (exons 1, 5, 6, and 7), and are intended to resolve CWD alleles (as defined by the October 2012 Revised Guidance ASHI Standards D.5.2.2.15).

To ensure that you experience no interruption in service while we complete the development process, we will continue to build enough of the current product to meet demand. Also, since the enhanced product will have the same Catalog ID as the current product, there will be no change in the ordering process as we bring the enhanced product online.

ONE LAMBDA DEVELOPS A REAL-TIME HLA TYPING ASSAY

We are pleased to announce the development of a real-time PCR HLA typing assay. Our new kit will use TaqMan® probe technology to detect amplification of genomic DNA on a real-time PCR instrument. We chose TaqMan chemistry because of the many advantages if offers, including:

  • Target specific amplification - Hybridization between probe and target is required to generate the fluorescent signal, resulting in greater assay specificity and lower signal-to-noise ratio.
  • Multiplexing capability - TaqMan probes can be labeled with different reporter dyes, allowing for the amplification and detection of multiple, distinct sequences in a single reaction.
  • Simple workflow - Change in the fluorescent signal for each channel and each well of the PCR tray is measured directly on the real-time PCR system, eliminating the need for gel electrophoresis and reducing assay labor and material costs.

The initial product offering will consist of a serological level resolution kit covering all HLA Class I (A, B, C) and Class II (DRB1, DRB345, DQA1, DQB1, DPA1, DPB1) loci. The RUO kit will be validated on multiple real-time instruments including the Viia™ 7, QuantStudio™ 6, and QuantStudio™ DX system. Data run files will be imported into HLA Fusion™ for analysis.

We are on track to release a Research Use Only kit in Q2-2016 and plans are in place to follow up with the release of CE-IVD and FDA (510k) cleared products. We will keep you updated on our progress.

 

 

 

It's Not Easy Going Green

Go Green. Go Paperless.

As you know, we’ve been working on going green for some time now. The benefits of switching from the 15th Century technology of printing important information on paper to the 21st Century technology of immediate digital delivery are too good to delay any longer.

The biggest challenge in making this kind of transition is to make sure that we are transitioning to something better. That’s what we’ve been working on since our Go Green Initiative started in 2014. This effort has included:

  • Making sure that user documentation is available on our website
  • Making sure that customers know how to find the documents they need

We’re pleased to announce that we’re coming to the end of this process and expect to complete the transition to digital delivery of all product documentation by the end of Q1, 2016.
