HCM145 Modified MSRV Agar Base

Introduction

Usages：
Determination of coliform and fecal coliform for multiple tube fermentation.
 
Principle:
Tryptone provide carbon and nitrogen sources to meet the needs of bacterial growth; sodium chloride osmotic pressure balance can be maintained; Lactose is a coliform fermentable sugars; potassium dihydrogen phosphate and dipotassium phosphate is a buffer; lauryl sodium can inhibit the growth of non-coliform bacteria.
 
Formulation (per liter):
Trypticase:20g
Sodium chloride: 5g
Lactose:5g
Potassium dihydrogen phosphate: 2.75g
Dipotassium hydrogen phosphate :2.75g
Sodium lauryl sulfate 0.1g
Final pH6.8 ± 0.2
 
How to use:
1. Suspend 35.6g of the product, adding 1 L of distilled or deionized water, heated to boiling stirring until completely dissolved, packed in a test tube with a small down tube, 121 ℃ autoclave 15min, leave to cool to room temperature, standby .
2.Sample handling and dilution.
3.Selected three consecutive dilution, each dilution was inoculated three LST broth tubes, each tube was inoculated 1mL.
4. Put the tubes in an incubator 36 ± 1 ℃ cultured for 48 ± 2h.
5. Observe the results. if all LST broth don’t pruduse gas, can be reported as negative for E. coli, if  gas production then will have to make further confirmed by experiments.
 
Quality control:
Quality control strains were inoculated and culuture at 36 ± 1 ℃ for 24h ,results are as follows:
Bacterial Name                 Bacterial No.          Growth Status       Gassing
Escherichia coli                ATCC25922               good              +
 
Salmonella typhimurium        CMCC (B) 50115            good             —
 
Staphylococcus aureus          ATCC6538                inhibited          —
 
 
Storage: Store in a dark, cool and dry place, tighten the cap immediately after use. Storage period of three years.
 
Specifications: 250g/bottle

Overview

• Removes primer dimers
• Simultaneously clean-up and normalize PCR products 
• Fast (less than 20 minutes), high-throughput and easy processing using centrifugation
• Sufficient elution volume (100 µL) for repeat or future assays 
• Non-magnetic bead purification 

Norgen’s NGS Normalization 96-Well Kit allows for high-throughput NGS library PCR amplicon clean-up and normalization of NGS library PCR product concentration. The clean-up removes all PCR by-products including primers, dimers, enzymes and unincorporated nucleotides during the library prep PCR step. Purification is based on 96-well column chromatography using Norgen’s proprietary resin as the separation matrix. The amount of Norgen’s matrix in each 96 well is optimized to have a limited binding capacity, thus each well can elute an equal concentration of PCR product. The process involves first adding 3 volumes of Buffer SK to the PCR product, and the mixture is then loaded onto the 96-Well Normalization Plate. The bound PCR amplicon is then washed with the provided Wash Solution A in order to remove any remaining impurities, and the purified PCR amplicon is eluted with Elution Buffer B. The purified and normalized library PCR amplicon can then be used in NGS workflows and other sequencing applications.
