Biotin-PEG8-DBCO is a PEG linker containing a DBCO moiety and a biotin group. The DBCO groups is commonly used for Click Chemistry reactions. The hydrophilic PEG chain allows for increased water solubility of compounds in aqueous media. The terminal biotinylation can react with amine molecules in the presence of activator EDC or HATU. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

The RNA Seq Library Prep Kit was developed for construction of high quality NGS libraries for next generation sequencing (illumina and MGI Platforms). RNA Sequencing is a very powerful tool to analyze transcriptome such as gene expression and transcription regulation, splicing characterization, mutation and variation detection etc. The kit needs purified RNA (example: rRNA depleted RNA or polyA mRNA) as input for library construction. Library multiplexing is possible with different types of indexes.
RNA Seq Library Prep Kit Workflow
Three index types are available for the illumina platform kits:
Non-index (illumina Cat.# 30055): Libraries do not have index.
Index (illumina Cat.# 30056): A unique barcode sequence with 6 bases has been included in each of the index primers. RNA Sequencing library multiplexing is possible with up to 48 samples. Index information can be downloaded here.
Unique dual index (illumina Cat.# 30057): RNA Sequencing library multiplexing up to 96 samples is possible with the unique dual indexes. We have developed a 4-Base Difference Index System. The system can generate indexes with at least 4 bases different from others in the 8-base indexing region. the unique dual indexing primers identify sequencing errors such as index hopping, mis-assignment, and de-multiplexing errors. Index information can be downloaded here.
Indexes are available for the MGI platform kits (Cat.# 34112).
Features
Comparison of the protocol time: BioDynami RNA Seq Library Prep Kit vs other vendors’ kits. Hands-on time and walk-away time were indicated.
Library size and distribution of BioDynami kit, 20 ng and 3 ng of polyA mRNA as input.
Comparison of library yield and duplication rate under the same condition: 20 ng and 3 ng of polyA mRNA were used as input. PCR cycle numbers were indicated.
Comparison of coverage of transcripts: 20 ng of polyA mRNA were used as input. BioDynami kit has more uniform coverage
Usages:
For selective enrichment of Salmonella.
Principle:
Peptone provide carbon and nitrogen sources to meet the needs of bacterial growth; lactose are fermentable sugars; selenite, sodium hydrogen inhibit Gram-positive bacteria and gram-negative enterobacteria most non-Salmonella; phosphate-buffered agent; L- cystine as a reducing agent.
Formulation(per liter):
Peptone: 5g
Lactose :4g
Sodium selenite: 4g
Disodium hydrogen phosphate: 10g
L- cystine: 0.01g
Final pH 7.0 ± 0.2
How to use:
1. Weigh 23g of the product , adding 1 L of distilled or deionized water , heated to boiling stirring until completely dissolved, dispensing flask, cooled to room temperature .
2. Pipette 10mL of pre-enrichment sample broth or 25mL and transferred species in the liquid sample flask in a sterile environment.
3.Place into incubator, cultured at 36 ± 1 for 18-24h.
4. Observe the results.
Quality control:
Quality control strains were inoculated ,and cultured at 36 ± 1 for 18-24h ,results show as follows:
strain name strain code growth feature
Salmonella typhi CMCC (B) 50071 good red, cloudy
Salmonella typhimurium CMCC (B) 50115 good red, cloudy
Escherichia coli ATCC25922 — remain unchanged
Storage: Store in a dark, cool and dry place, tighten the cap immediately after use. Storage period of three years.

Norgen’s Trichomonas vaginalis End-Point PCR Kit is designed for the detection of Trichomonas vaginalis specific DNA based on the use of end-point PCR technology. This kit is designed for research use only and not for use in diagnostic procedures. The kit includes Master Mix and primers for the specific amplification of a 335 nucleotide region of the Trichomonas vaginalis genome, as well as a positive control and a negative control to confirm the integrity of the kit reagents. In addition, the kit contains loading dye and a DNA ladder to facilitate analysis of the results.
The detection of Trichomonas vaginalis specific DNA is based on end-point PCR technology, utilizing polymerase chain reaction (PCR) for the amplification of specific Trichomonas vaginalis DNA sequences. For analysis of the PCR data, the PCR reaction is loaded on an agarose DNA gel along with the provided DNA ladder for qualitative analysis.

Storage Conditions and Product Stability
All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
