t-Boc-N-Amido-PEG5-propargyl comprises a propargyl group and Boc-protected amine. The propargyl group reacts with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. The Boc group can be deprotected under mild acidic conditions to form the free amine. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Attogene’s Microcystin Test Kit (Rapid – Lab) can be used to detect microcystins in liquid samples.
The most frequently reported cyanobacterial toxins are the hepatotoxic microcystins (MCs). MCs are peptides with a molecular weight ranging from 900 to 1,100 Da. They consist of seven amino acids of which the two terminal amino acids of the linear peptide are condensed to form a cyclic compound.
A tiered notification system which takes different actions based on different numeric thresholds for microcytin-LR concentrations in recreational waters has been developed. This is guidance that allows states to take various actions—such as posting information about harmful algal blooms (HABs), issuing a recreational public health advisory, or temporarily closing recreational waters through a no contact advisory—depending on the severity of the bloom event.
Microcystin-LR
Informational sign postings about HABs at recreational waters: < 6 μg/L
Recreational public health advisory: 6 μg/L
Elevated recreational public health advisory (e.g. no contact): 20 μg/L

The Digestible and Resistant Starch Assay Kit (K-DSTRS) for the determination of digestible, resistant and total starch in starch samples, plant and other materials.
This method is based on the research of Englyst et al. (Ref) with some modifications. Digestion is performed using saturating levels of pancreatic α-amylase (PAA) and amyloglucosidase (AMG), but in stirred containers rather than shaken tubes, to simplify sample removal.
In line with Englyst definitions:
Rapidly digestible starch (RDS) is that starch which is digested within 20 min.
Slowly digestible starch (SDS) is that starch which is digested between 20 and 120 min.
A new term, ‘Total digestible starch (TDS)’ is introduced (and measured) to cover all starch that is digested within 4 h (the average time of residence of food in the human small intestine).
Resistant starch (RS) then, is that starch which is not digested within 4 h.
The incubation conditions parallel those used in AOAC Method 2017.16, a new, rapid integrated procedure for the measurement of total dietary fiber (Megazyme method K-RINTDF). This method is physiologically based and designed to fit the definition of DF announced by Codex Alimentarius in 2009.
