Usages:
For selective enrichment of Salmonella.
Principle:
Peptone provide carbon and nitrogen sources to meet the needs of bacterial growth; lactose are fermentable sugars; selenite, sodium hydrogen inhibit Gram-positive bacteria and gram-negative enterobacteria most non-Salmonella; phosphate-buffered agent; L- cystine as a reducing agent.
Formulation(per liter):
Peptone: 5g
Lactose :4g
Sodium selenite: 4g
Disodium hydrogen phosphate: 10g
L- cystine: 0.01g
Final pH 7.0 ± 0.2
How to use:
1. Weigh 23g of the product , adding 1 L of distilled or deionized water , heated to boiling stirring until completely dissolved, dispensing flask, cooled to room temperature .
2. Pipette 10mL of pre-enrichment sample broth or 25mL and transferred species in the liquid sample flask in a sterile environment.
3.Place into incubator, cultured at 36 ± 1 for 18-24h.
4. Observe the results.
Quality control:
Quality control strains were inoculated ,and cultured at 36 ± 1 for 18-24h ,results show as follows:
strain name strain code growth feature
Salmonella typhi CMCC (B) 50071 good red, cloudy
Salmonella typhimurium CMCC (B) 50115 good red, cloudy
Escherichia coli ATCC25922 — remain unchanged
Storage: Store in a dark, cool and dry place, tighten the cap immediately after use. Storage period of three years.

Designed for those labs wishing to separate magnetic beads into rings.
The Permagen ring magnet low elution plate with integrated cushion base plate was designed for use in automation applications where volumes as low as 5 µL are required. Most PCR plates are bent, leading to inconsistent lab results. Unlike most products, we have added an angled frame around the top of our plate, this helps with two things, straightening out the PCR plate, and leading it to the proper location on the magnets during automation while the cushion assist compensates for labware inconsistencies.
SBS SLAS Footprint (127.75mm x 85.50mm) to fit into any automated liquid handling robot
Features include solid aluminum alloy construction and hard coat anodized finish for years of trouble-free use, and compatible with any magnetic beads
RLE500R
Maximum – 150 µL
Minimum – 5 µL

Sulfo DBCO-Amine can be used to derivatize carboxyl-containing molecules or activated esters (e.g. The NHS ester) with DBCO moiety through a stable amide bond. The low mass weight will add minimal spacer to modified molecules and the hydrophilic sulfonated spacer arm will greatly improve water solubility of DBCO derivatized molecules. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
