[CD3000] SMOChem™ dATP Solution – Sodium Salt (100 mM), 25ml

Overview

• No need for staining and destaining of denaturing gels since Norgen’s loading buffer contains ethidium bromide
• Highly stable
• Nine bands from 200 bases to 4000 bases
• Convenient lyophilized format provides better product stability

The Norgen 1 kb RNA Ladder is a set of RNA transcripts derived from recombinant DNA templates. This ladder is suitable for precise sizing of a wide range of RNA molecules using native or denaturing agarose gels, and can be visualized under UV.

Contents: 
• 2 vials of lyophilized RNA ladder (25 loads each)
• 1x loading buffer: 33.3% formamide, 11.7% formaldehyde, 0.012% bromophenol blue, 0.05mM EDTA, 0.012% ethidium bromide, and 0.7x MOPS solution
• 2x loading buffer

Specifications:
• Nine discrete bands, ranging from 200 to 4,000 bases
• Higher intensity band at 1,000 bases for easy reference

Contents:
• 2 vials of lyophilized RNA ladder (25 loads each)
• 1x loading buffer: 33.3% formamide, 11.7% formaldehyde, 0.012% bromophenol blue, 0.05mM EDTA, 0.012% ethidium bromide, and 0.7x MOPS solution
• 2x loading buffer

Instructions:
To reconstitute the lyophilized RNA ladder, add 250 µL of 1x loading buffer to each 25 loads vial and vortex gently.
Heat at 80°C for 10 minutes. Incubate on ice for 1 min. Load 10 µL on a 1-2% gel. For optimal results, use Norgen 2x loading buffer with each RNA sample. No need for staining and destaining of denaturing gels since Norgen’s loading buffer contains ethidium bromide.

Store at -20°C.

Introduction

Intended Use

For enriching bile-tolerant Gram-negative bacteria in the microbiological examination of pharmaceutical products.

Principle and Interpretation

Pancreatic digest of gelatin provide protein, vitamins and amino acids; glucose carbon source; disodium hydrogen phosphate and potassium dihydrogen phosphate as a buffer; ox bile and brilliant green as selective antibacterial agent, inhibiting the growth of non-Enterobacteriaceae.

Formulation

Ingredients	/liter
Pancreatic digest of gelatin	10g
Glucose monohydrate	5g
Dehydrated ox bile	20g
Potassium dihydrogen phosphate	2g
Disodium hydrogen phosphate dihydrate	8g
Brilliant green	15mg
pH7.2±0.2 at 25°C

Preparation

Suspend 45g in 1L of distilled water,stir until completely dissolved and dispense 100 mL into test tubes , heat at 100 °C for 30 min in a waterbath or flowing steam.

Quality Control

The following quality control strains were inoculated and cultured at 30-35℃ for 24h-48h. The results are as follows:

Quality control strains	Inoculum (CFU)	Growth
Escherichia coli ATCC8739	< 100	Good growth
Pseudomonas aeruginosa ATCC9027
Staphylococcus aureus ATCC6538	> 100	Inhibited

Storage and Shelf Life

2-30℃，Keep container tightly closed, avoid direct sunlight.

Use before expiry date on the label.

 Precautions

1. When weighing the dehydrated medium, please wear masks to avoid causing respiratory system discomfort

2. Keep container tightly closed after using to prevent clumping.

Waste Disposal

Microbiological contamination was disposed by autoclaving at 121°C for

30 minutes.
