Curriculum, including Teacher's Guide, Student Manual, and graphic Quick Guide
Microbial Culturing: As part of the Cloning and Sequencing Explorer Series.
Select for positive ligations and grow bacterial minipreps. Students use this module to prepare media for their microbiological needs for the Cloning and Sequencing Explorer Series.
Starter cultures are required for competent cell preparation. Students will make LB agar plates and streak them with E. coli bacteria for single colonies. Students then prepare LB broth to make an overnight starter culture from their streaked plate, which is used to prepare competent cells using the ligation and transformation module.
LB ampicillin agar plates are required to select for bacteria that have been transformed with plasmids — like pJET1.2 — which contain the Β-lactamase gene conferring ampicillin resistance to bacteria. After transformation, bacteria are plated onto LB ampicillin agar plates and incubated at 37°C and ampicillin resistant bacterial colonies will grow overnight.
LB broth containing ampicillin is required to culture minipreps grown from colonies transformed with ligated plasmid. Plasmids are then isolated from the minipreps using the Aurum plasmid mini purification kit.
The Microbial Culturing module contains the materials necessary to teach basic sterile technique, culture and transform ampicillin-resistant E. coli, and grow cultures for plasmid minipreps.
I cannot find the Certificate of Analysis I am looking for. Help!
When using our online Certificate of Analysis search tool, keep the following in mind:
Make sure you entered the correct catalog number and lot/control number in the search fields
If you have a kit, try looking up the Certificate of Analysis using the kit information as well as the information for the individual components
The Certificate of Analysis that you are looking for may not be available via the website. In that case, you can contact your Bio-Rad representative or use the Request Form
If you cannot find the Certificate of Analysis you are looking for, please Contact Us.
Where can I find the catalog number, SKU number, or product number?
The catalog number, SKU number, or product number is printed on your product label. See the sample label below for the location of this information.
Where can I find the lot or control number?
The lot number or control number (one or the other, not both) is printed on your product label. See the sample label below for the location of this information.
Why are Certificates of Analysis not on the Documents tab?
Certificates of Analysis are associated not only with a product, but also with a specific lot of that product. For a given product, there may be several Certificates of Analysis, especially if it is an older product line and has had several lots produced over the years. Using the Certificate of Analysis search tool, you can enter the catalog number and lot/control number for the specific product you have on hand and download the exact Certificate of Analysis you need.
I have a batch number, not a lot/control number. How do I find the Certificate of Analysis for my item?
You can use the batch number in place of the lot/control number. Use the Certificate of Analysis search tool, entering the catalog number as usual and the batch number where the lot/control number would go.
Can I get a Certificate of Analysis even if my item is expired?
Yes. While we do periodically remove Certificates of Analysis for site maintenance purposes, we typically keep them available well beyond a product's expiration date.
Why does it say "Product Name Not Found" for a Certificate of Analysis listed in the search results?
There are Certificates of Analysis that correspond to products that are either discontinued or simply not available on the website. In these situations, the Certificate of Analysis is available for download, but other product details, such as the product name, are not.
Why does it say "Not Available" for a Certificate of Analysis listed in the search results?
In this case, you have entered a valid catalog number and lot/control number and we have located the Certificate of Analysis. However, for some reason, the actual file itself is unavailable.
Please use the Request Form here or contact your local Bio-Rad Representative so that we can send you the Certificate of Analysis.
