Detail
The Permagen 384-well post magnet plate was designed for use in manual or automation applications for Low Elution high throughput PCR
Magnetic beads are pulled midway up onto well wall to help eliminate accidental bead pellet disruption and to achieve lower volumes
Features include solid aluminum alloy construction and hard coat anodized finish for years of trouble-free use, compatible with any magnetic beads, and integrated cushion base to help aid in robot/ consumable inconsistencies
PEG3-bis(Amino-Tri-(Propargyl-PEG8-ethoxymethyl)-methane) is large molecule with two sets of three terminal alkynes joined together by a short PEG linker. The alkynes are most frequently used in copper click chemistry with azides to form stable triazoles with the target compound. The PEG linkers as well as numerous amide bonds provide high aqueous solubility to this compound, which may alter DMPK of this compound.

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%.
