Principles
This product is based on silica column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, Nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).
Advantages
High quality DNA – meet a variety of downstream applications, including PCR, qPCR, enzyme digestion, hybridization, etc.
Fast – without separation of leukocytes, organic extraction or ethanol precipitation
Simple – all nucleic acids can be obtained by direct digestion
Wide applicability – handle a variety of liquid samples

Storage and Stability
Proteinase K, RNase A should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions.
*Note：Leukocyte protocol can be used when large volume whole blood samples need to be processed. Whole blood was treated with red blood cell lysate, and white blood cells were obtained by centrifugation before extraction

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.
Optimum activity at high salt concentration (0.5 M NaCl)
Active at low temperatures (20% at 6ºC)
Easily inactivated
Broad pH range
Temperature stable
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%.
