Propargyl-PEG4-methylamine is a PEG linker that can be react with azide compounds in copper catalyzed azide-alkyne Click Chemistry reactions. The methylamine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The PEG spacer increases hydrophilicity of the linker in aqueous environment. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

The Hepatitis B virus (HBV) is mainly transmitted via blood or blood products. In addition, sexual, oral and perinatal infections are also possible. Early symptoms of the infection include appetite loss, vomiting and abdominal symptoms, with approximately 10-20% of those patients developing fever as well as rheumatoid joint and muscle pain. Jaundice, which may be accompanied by itching, will then develop within 2-14 days. Fulminant hepatitis then occurs in about 1% of all infected patients, which in severe cases may be fatal. Of those individuals infected by HBV, 5-10% will develop chronic liver inflammation which may progress to cirrhosis of the liver or, in the worst case, primary liver cell carcinoma. The HBV virus is a hepadnavirus that has a circular genome composed of partially double-stranded DNA.

PACE Genotyping Master Mix uses a novel, universal, fluorescent reporting cassette to produce machine-readable fluorescent signals corresponding to genotypes. PACE compatible genotyping assays are comprised of two competitive allele specific forward primers (which differ in their terminal 3’ bases and unique 5’ tail sequences) and a common, reverse primer. PACE Genotyping Master Mix is supplied at 2x concentration and with ROX normalising dye at a range of levels to ensure compatibility with your qPCR instrument or reader.
Genotyping assay designs are available from 3CR Bioscience through our free PACE assay-design service; once designed, users can purchase assay primers independently or through 3CR Bioscience using our partial or full-assay validation service. PACE Genotyping Master Mix is also compatible with KASP™ and Amplifluor® marker assays.

Usages:
For isolating lactose-fermenting Gram-negative enteric bacilli.
Principle:
Peptones are sources of nitrogen and other nutrients. Lactose is a fermentable carbohydrate. When lactose is fermented, alocal pH drop around the colony causes a color change in the pH indicator (neutral red) and bile precipitation. Bile salts,bile salts no. 3, oxgall and crystal violet are selective agents that inhibit growth of gram-positive organisms. Agar is the solidifying agent.
Formulation（per liter）:
| Pancreatic Digest of Gelatin | 17.0 g |
| Peptones (meat and casein) | 3.0 g |
| Lactose Monohydrate | 10.0 g |
| Sodium Chloride | 5.0 g |
| Bile Salts | 1.5 g |
| Agar | 13.5 g |
| Neutral Red | 30.0 mg |
| Crystal Violet | 1 mg |
| Final pH | 7.1±0.2 |
How to use：
1.Suspend 50 g in 1 L of distilled or deionized water. Heat to boiling to dissolve completely. Autoclave at 121°C for 15 minutes.
2.Transfer 1 mL of Soybean–Casein Digest Broth to 100 mL of MacConkey Broth, and incubate at 42 to 44 for 24 to 48 hours. Subculture on a plate of MacConkey Agar at 30 to 35 deg.C for 18 to 72 hours.
Quality control：
