The lectin has a molecular weight of 110 kDa and consists of four identical subunits of approximately 27 kDa each. PNA is a carbohydrate-free protein that displays specificity towards ?-D-Gal(1-3)-D-galNAc. It has potent anti-T activity and can be used to distinguish between human lymphocyte subsets. PNA has been used in tumour tissue determination for transitional mucosa malignancies. The lectin also agglutinates neuraminidase-treated human erythrocytes at < 0.1 µg/ml after trypsin treatment of cells and its activity is inhibited by lactose and galactose. PNA lectin is provided as a white to light yellow lyophilized powder from a buffer containing 10 mM NH4HCO3. The purity is determined by SDS-PAGE, which generates one band at 25-27 kDa.● Ultrapure quality ● Strong anti-T activity ● Sugar specificity: ?-D-Gal-(1-3)-D-GalNAc ● Agglutinates rabbit erythrocytes at < 0.1 µg/ml after trypsin treatment of the cells ● Lyophilized powderProbe in histochemistry and immuno-histochemistry;Human erythrocyte/lymphocyte studies...

Endoglycosidase F1 will hydrolyze sulfate containing high-mannose chains. It cleaves between the two N-acetylglucosamine residues in the Product DescriptionEndo F1 cleaves Asparagine-linked high mannose and some hybrid oligosaccharides. Core fucosylation reduces the activity by 50 fold. Endoglycosidase F1 will hydrolyze sulfate containing high-mannose chains. It cleaves between the two N-acetylglucosamine residues in the diacetylchitobiose core of the oligosaccharide, generating a truncated sugar molecule with one N-acetylglucosamine residue remaining on the asparagine. In contrast, PNGase F removes the oligosaccharide intact.Molecular weight 32,000 daltonsContents60 µl aliquot of enzyme (1 U) in 20 mM Tris-HCl, pH 7.5Included with 20 µL and 60 µL pack sizes:5x Reaction Buffer – 250 mM sodium phosphate, pH 5.5Specific ActivityDefined as the amount of enzyme required to catalyze the release of N-linked oligosaccharides from 1 micromole of denatured Ribonuclease B (RNase B) in 1 minute at 37°C, pH 5.5. Cleavage is monitored by SDS-PAGE (cleaved RNase B migrates faster).FormulationThe enzyme is provided as a sterile-filtered solution in 20 mM Tris-HCl, pH 7.5StabilitySeveral days exposure to ambient temperatures will not reduce activity. Stable at least 12 months when stored properly. SpecificityEndo F1 cleaves Asparagine-linked high mannose or hybrid oligosaccharides. It cleaves between the two N-acetylglucosamine residues in the diacetylchitobiose core of the oligosaccharide, generating a truncated sugar molecule with one N-acetylglucosamine residue remaining on the asparagine. In contrast, PNGase F removes the oligosaccharide intact. Quality & PurityEndo F1 is tested for contaminating protease as follows: 10 µg of denatured BSA is incubated at 37°C for 24 hours with 2 µl of enzyme. SDS-PAGE analysis of the treated BSA shows no evidence of degradation. The production host strain has been extensively tested and does not produce any detectable glycosidases.Directions for use1. Add up to 200 µg of glycoprotein to an Eppendorf tube. Adjust to 38 µl final volume with de-ionized water.2. Add 10 µl 5x Reaction Buffer 5.53. Add 2.0 µl of Endo F1 to the reaction.

A stable blue precipitate is formed at the reaction site. The substrate does not contain NMP (1-methyl-2- pyrrolidone) making it REACH Restricted Substances List Annex XVII compliant, while ensuring maximal safety during use, and minimal waste problems after use.Composition & Properties Ready-to-use substrate: Includes substrate buffer and hydrogen peroxide. No other reagents should be added.Working Procedure The following procedure is applicable to nitrocellulose membranes. The procedure must be optimized for other membranes.1.The desired amount of substrate is poured into a sealed container and allowed to reach room temperature, in the dark, before use. 2.After the last incubation with HRP-labelled Streptavidin or HRP-labelled secondary antibody it is recommended to wash the membrane in a 0.1 M Tris buffer pH 7.4.3.Shake off the excess buffer and incubate the membrane in the TMB-D Blotting solution for 10 minutes. 4.Wash the membrane in distilled water and allow it to dry. 5.The site of positive reaction will appear light blue with no or very little background staining.Tips & Tricks • The membrane can be blocked with Kementec’s Synthetic Blocking Buffer for Blotting, (cat. no. S494457). • For long-term preservation of the results, the membranes must be stored in the dark.Handling & Storage • Store solution at 2-8⁰C in the dark. • Avoid exposure to light, heat and contamination with metal ions or peroxidase. • Re-dispense only into bottles made of High-Density Polyethylene (HDPE), amber color.
