N-(t-butyl ester-PEG2)-N-bis(PEG2-propargyl) is a multi-functional PEG linker with two terminal propargyl groups and a t-butyl ester. The propargyl groups enables formation of triazole linkage with azide-bearing compounds or biomolecules in copper catalyzed Click Chemistry. The t-butyl protected carboxyl group can be deprotected under mild acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

The kits were developed for plasmid miniprep directly from bacterial cultures. 100% centrifuge-free; NO vacuum needed; No column needed.
Plasmid MiniPrep Kit (Magnetic Beads), Cat.# 50012
– Use 2 ml of bacteria culture directly
Plasmid MiniPrep High Throughput Kit (Magnetic Beads), Cat.# 50011
– High throughput: Use 0.2 ml of bacteria culture directly with 96-well plates
– Low throughput: Use 0.2 ml of bacteria culture directly with 1.5 ml tubes
The kits can be used for both high copy and low copy numbers of plasmid DNA. With BioDynami’s proprietary magnetic beads technology, the kits eliminate the requirement of centrifuge, vacuum, and column. Our magnetic beads provide a robust and reliable tool for both high throughput and low throughput applications of plasmid DNA isolation with high binding capacity and fast magnetic response time.
The High Through kit (Cat.# 50011) can be used for both high throughput and low throughput extraction of plasmid DNA. Up to 96 samples can be extracted simultaneously when using a 96-well plate.
Yield of plasmid DNA may vary dependent on the bacteria strain, plasmid type, copy numbers, and growth conditions etc. DNA extracted using the kit is suitable for downstream applications such as qPCR, PCR, DNA sequencing, molecular cloning, restriction enzymatic digestion, transfection, and transformation etc. The isolated plasmid DNA with the magnetic beads is free of contaminations such as RNA, bacterial DNA, proteins, and other impurities.
Plasmid DNA were loaded on 1% of agarose gel after extraction.

Features
Saxitoxins (STXs) are naturally occurring alkaloids produced by some marine dinoflagellates and by strains of various species of freshwater cyanobacteria. Saxitoxin is one of the prevalent paralytic shellfish toxins (PSTs). It belongs to a family of potent neurotoxins with a molecular weight around 300 Da. Saxitoxin and its derivatives are alkaloids composed of a tetrahydropurine ring system with a highly polar guanidinium group. Due to their significant toxicity, saxitoxins are closely monitored in marine environments where they can accumulate in the food chain during harmful algal blooms (HABs). An action level of 800ppb, or 80ug per 100grams of shellfish, has been established.
Screening of saxitoxin in shellfish samples as low as 50ppb in sample
Format: 25 tests (12 tests, 12 controls)
Filters, syringes, extract collection tubes, buffers
