Usages: For the growth of pathogenic and non-pathogenic microorganisms.
Principle: Polypeptone provide carbon and nitrogen sources, vitamins and growth factors; Neisseria starch can promote the growth characteristics and enhanced hemolytic streptococci; sodium chloride to maintain osmotic balance; agar as culture medium coagulant.
Formulation (per liter): Peptone: 10g Beef extract powder :10g Sodium chloride: 5g Agar :15g Final pH 7.4 ± 0.2
How to use: 1. Suspend 40g of the product, adding 1 L of distilled or deionized water, ,heated to boiling stirring until completely dissolved, dispensing into flask, 121 autoclaved 15min. 2.After the medium is cooled to about 50 , sterile procedures, basal medium was added per 100mL defibrinated sheep or rabbit blood 5-10mL, shake pour plate; also dispensing sterile tubes set into the slope. Spare. 3. take the bacteria to be tested fresh pure cultures inoculated crossed or coated on the plate, set the temperature of the incubator training requirements were cultured for a predetermined time. 4. Observe the results.
Quality control: The following were inoculated after 36 ± 1 for 24h , the results are as follows: bacteria name bacteria No. growth status colony characteristics Escherichia coli ATCC25922 not good hemolysis
Staphylococcus aureus, ATCC6538 good β-hemolytic
Beta-hemolytic streptococcus CMCC (B) 32210 good β-hemolytic
Streptococcus pneumoniae CMCC (B) 31001 good α-hemolytic
Storage: Store in a dark, cool and dry place, tighten the cap immediately after use. Storage period of three years.
Organophsphates are a class of pesticides that mechanistically target the acetylcholinesterase enzyme. Regulatory guidelines have been set to ensure our food and water are within the acceptable regulatory authority guidelines. Because most OPs are provided in their precursor form, organothiophosphate (i.e., Malathion, Diazinon, Chlorpyrifos, Azinphos, Dimethoate, Terbufos, Phosmet) Attogene’s organophosphate ELISA kit has been designed to detect organothiophosphates which are the main form of the compounds when applied in the field.
Document
This kit can be used for rapid test of organophosphate in liquid samples such as water, wastewater, and solid samples such as wheat.

Permagen’s 16 x 1.5 mL Microfuge Tube Magnetic rack is designed for magnetic bead separations from up to 16 tubes
Contains the strongest magnets out of all of our Microfuge racks
Tubes are pushed 14mm between centers allowing the use of an 8-channel, adjustable head pipette. 8 tubes per side also make for easy transition to and from microplates
Accommodates many common 1.5 mL Microcentrifuge and some 2.0 mL tubes
Tubes are angled and beads will be pulled to back wall allowing easy aspiration and tip tracking down the front wall of the tubes without disturbing bead pellet
