Detail
Overview
Adhesive film with 96 optically clear windows. This seal is peelable, suitable for qPCR and optical applications.
These unique seals combine the strong sealing integrity of our QuickSeal PCR Seal with improved optical properties, thanks to the 96 adhesive-free windows
The seal is made of a durably transparent polyester film, and a strong adhesive is applied across the seal, apart from the 96 round windows
The QuickSeal qOptic seal is recommended for qPCR and other optical applications, such as fluorescence or colorimetric measurements
For all adhesive seals, the best sealing results are achieved using our Hand Roller or KAPS 500 Auto Sealer

Introduction
This product is designed for purification of high-molecular-weight genomic or mitochondrial DNA from a variety of blood samples. High-quality DNA can be purified from sample types including whole blood, buffy coat, bone marrow, body fluids in as little as 25 minutes. The convenient, scalable purification procedure removes contaminants and enzyme inhibitors such as proteins and divalent cation, and purified DNA is ready for immediate use in sensitive downstream applications or for archiving.

Main Functions
Isolation total DNA from whole blood using economic salt out method
Cells are lysed with ananionic detergent in the presence of a DNA stabilizer. The DNA stabilizer limits the activity of intracellular DNases and also DNases found elsewhere in the environment. RNA is then removed by treatment with an RNA digesting enzyme. Other contaminants, such as proteins, are removed by salt precipitation. Finally, the genomic DNA is recovered by precipitation with alcohol and dissolved in Buffer TE. Purified DNA typically has an A260/A280 ratio between 1.7 and 1.9, and is up to 200 kb in size. The DNA can be safely stored at 2-8°C, -20°C, or -80°C.
Advantages
Safe – without phenol chloroform extraction
Environment friendly – the reagents used are safe, non-toxic and without pollution
High molecular weight – the molecular weight of genomic DNA is about 50-150kb
High purity – the purified DNA has A260/280=1.8-1.9, A260/230=2.0-2.5
Unlimited sample size – solution type operation, sample volume can be adjusted at will
Cost performance – the most economical nucleic acid extraction technology

Storage and Stability
RNase Solution should be stored at 2-8°C upon arrival. However, short-term storage (up to 24 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2-8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.

HL-SAN efficiently removes nucleic acids from buffers typically used in protein purification. Due to its high salt tolerance, it is the obvious choice for host-cell DNA removal in settings where salt is added to reduce aggregation. Especially efficient for removing nucleic acids from proteins with high affinity for DNA and RNA. Proven performance during lysis and early stages of protein purification processes, as well as high-salt eluates. Cold-adapted enzyme with excellent performance also at ambient temperatures and during over-night digestion at 4°C.

Figures
Figure 1. Optimum activity in solutions with high salinity
HL-SAN has optimum activity at ∼0.5 M NaCl, but operates at a broad range of [NaCl] and [KCl]. The activity of HL-SAN was tested in a 25 mM Tris-HCl buffer, pH 8.5, 5 mM MgCl2 with varying [NaCl] or [KCl]. The maximum activity was set to 100%.
Figure 2. Temperature and activity
HL-SAN has optimum activity at ~35°C, but works over a broad temperature range (20% activity at 10°C and 50°C). The activity of HL-SAN was tested in a 25 mM Tris-HCl buffer, pH 8.5 containing 5 mM MgCl2 and 0.5 M NaCl.
Fig 3. The effect of MgCl2 and MnCl2 concentration on the HL-SAN activity.
The activity of HL-SAN was tested in a 25 mM Tris-HCl buffer, pH 8.5, 0.5 M NaCl and with varying concentrations of MgCl2 or MnCl2. The activity of the sample containing 5 mM MgCl2 was set to 100%.
Figure 4. HL-SAN activity vs pH/[NaCl]
The activity of HL-SAN was tested in a 25 mM Tris-HCl buffer with different pHs and different concentrations of NaCl. All buffers contained 5 mM MgCl2. The nature of the buffer was pH-dependent, but generally the NaCl-optimum was the same in all buffers/pHs. The exception was etanolaminbuffer at pH 9 and pH 9.5 in which the NaCl-optimum was shifted to the left (not shown).
Without NaCl, the specificity towards ssDNA and dsDNA is similar. At 0.5 M NaCl, the activity towards dsDNA increases, while the activity towards ssDNA is unaffected.
Figure 6. HL-SAN digests ssDNA to ~5-13 nt, and dsDNA to ~5-7 nt
The size of the end products from ssDNA varies from ~5-13 nt, while dsDNA is digested to around ~5-7 nt. The size of the end products seems to depend on the DNA sequence. Substrates 1 and 2 were ssDNA with different sequences and substrates 3 and 4 were dsDNA with similar sequences but with a FAM-label at different ends. Substrate 5 was dsDNA with the same sequence as substrate 3 and 4 but with a FAM-label at both ends.
Figure 7. HL-SAN activity decreases with increasing concentrations of glycerol
The activity of HL-SAN was tested in a 25 mM Tris-HCl buffer, pH 8.5, 5 mM MgCl2, 0.5 M NaCl and with increasing concentrations of glycerol. The activity of the control not containing glycerol was set to 100%.
Figure 8. The activity of HL-SAN at different concentrations of imidazole
The activity of HL-SAN was tested in a 25 mM Tris-HCl buffer, pH 8.5, 5 mM MgCl2, 0.5 M NaCl and with varying concentrations of imidazole. The activity of the control not containing imidazole was set to 100%.
