029100 Urea Solution 40percent

Introduction

Usages:

For the rapid detection and enumeration of Escherichia coli.

Principle:

Peptone and yeast extract powder provides carbon and nitrogen sources and trace elements; sodium chloride maintains osmotic equilibrium; agar as medium coagulant; dodecyl sulfate inhibit Gram-positive bacteria; chromogenic substrate and large intestine coli β- glucuronidase enzyme specific reaction, hydrolysis of the substrate, the release of the color groups produce green colonies on the light yellow plate.

Formulation (per liter):

Peptone :15.0g

Yeast extract powder: 3.0g

Sodium chloride: 5.0g

Sodium lauryl sulfate:0.1g

Agar: 12.0g

Chromogenic substrate 6.5g

Final pH 7.0 ± 0.2

How to use:

1. Weigh 41.6g of the product, adding 1.0L distilled or deionized water, heated to boiling stirring until completely dissolved, dispensing into flask, 115 autoclaved for 10minutes.

2. Take 25.0g or 25.0ml of sample with sterile procedures , added  to the flask containing 225.0mL of sterile phosphate buffered saline (or saline) , shaken thoroughly homogenized with a homogenizer or a 1:10 dilution of 1min solution, diluted 1:10 and then continue to select the appropriate serial dilutions of three, the two plates inoculated with each dilution, poured dissolved by heating and cooled to about 45 medium.

3, observe the results.

Quality Control

This product appears light yellow after the pouring on plate, these strains were inoculated after 36 ± 1 18 ~ 24h culture growth in the following table.

LyoCakes are ready-to-use, freeze-dried master mixes pre-aliquoted PCR-strips or reaction-tubes.

LyoCakes contain: DNA polymerase(s), reaction buffer, dNTPs and primers and probes. They are rehydrated within seconds in any aqueous solutions, which  makes reaction setup very easy. Simply add a biological sample and place the tube in a PCR cycler. 

Storage: LyoCakes are shipped and stored simply at room-temperature. This provides a more cost efficient and ecological distribution compared to other master mixes.

As this is a customized product, we take your requirements very serious. You would like to know more? Please get in touch!

The Multiplexing Index Primers contain primer mix for multiplexing library samples for Next Generation Sequencing (NGS) on the illumina platform. Multiplexing of NGS library samples will reduce sequencing costs by pooling multiple NGS libraries into a single flow cell lane.

With library multiplexing, unique index sequence is added to individual sample during NGS library preparation.  Therefore, each DNA molecule can be identified after pooling of multiple samples based on the index information they have.

Each of our index primers contains a unique index sequence with 6 bases that can be used to identify libraries. Library multiplexing up to 48 samples is possible.

Multiplexing Index Primers (illumina platform): Even distribution of 48 samples using index primers. 48 libraries were made using the BioDynami NGS DNA Library Prep Kit (Cat. # 30009) and the BioDynami Multiplexing Index Primers (Cat. # 30072). Libraries were pooled at equal concentration and sequenced on the illumina HiSeq 2500. The numbers of reads from 48 libraries were analyzed.

List of index sequence for the primers (each of the index primer mix contains universal primer and one of the index primers). Index number and the index sequence are listed.
