DBCO-PEG13-DBCO is a long chain click chemistry reagent DBCO will react with azide-bearing compounds or biomolecules without copper catalyst. The hydrophilic PEG spacer arm can increase water solubility and membrane permability. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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.
| Ingredients | /liter |
| Pancreatic digest of gelatin | 10g |
| Glucose monohydrate | 5g |
| Dehydrated ox bile | 20g |
| Potassium dihydrogen phosphate | 2g |
| Disodium hydrogen phosphate dihydrate | 8g |

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.
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 |
2-30℃，Keep container tightly closed, avoid direct sunlight.
Use before expiry date on the label.
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.
Microbiological contamination was disposed by autoclaving at 121°C for
30 minutes.

Introduction
This Kit is designed to purify genomic DNA and total RNA simultaneously from a single biological sample. Lysate is first passed through a DNA spin column to selectively isolate DNA and then through an RNA column to selectively isolate RNA. Pure DNA and RNA are purified from the entire sample, in contrast to other procedures where either the biological sample or the purified total nucleic acids is divided into two before being processed separately. The kit is compatible with small amounts of a wide range of animal cells and tissues.
Specifications
| Features | Specifications |
| Main Functions | Co-isolation DNA and RNA(not include miRNA) from a single sample (cells, soft tissue, plant sample) |
| Applications | RT-PCR, cDNA synthesis, PCR andsecond-generation sequencing, etc. |
| Purification method | Mini spin column |
| Purification technology | Silica technology |
| Process method | Manual (centrifugation or vacuum) |
| Sample type | Soft tissue samples (viscera, excluding skin andmuscle), cultured cells and common plant tissues |
| Sample amount | Soft Tissue: < 30mg, Cell: <1 x 107, Plant: <100mg |
| Yield | DNA: 1 – 20 μg, RNA: 3 – 100 μg |
The Kits are designed to purify both genomic DNA and total RNA from the same cellor tissue sample. Samples are first lysed and homogenized. The lysate is passed through a DNA Mini column and bind DNA. Ethanol is added to the flow-through and the sample is applied to an RNA column. DNA/RNA binds to the membrane and contaminants are washed away. High-quality RNA is eluted in as little as 30µl water using the Kit. High-quality DNA is eluted in as little as 50µl water using the Kit.
