Continued from Part I This second in a two-part series provides an overview of some important areas relevant to preparing for the U. It includes discussions on microbial culture maintenance, growth media, biochemical reagents, test procedures, documentation and investigations. The importance of preparation for an inspection cannot be underestimated. Excerpt Only This is a shortened version or summary of the article you requested. To view the complete article, please log in or create an account. In general, it is common practice to limit the use of microbial cultures to no more than five passages or transfers from an original American Tissue Culture Collection ATCC vial. The purpose for this limitation is to prevent phenotypic drift in the appearance of microbial growth for a culture. In addition, proper documentation should be kept to confirm the identity of the used stock cultures.

How to Keep Your Lab Stockroom and Reagents Organized How to Keep Your Lab Stockroom and Cold Reagents Organized There are few things more frustrating in the lab than planning and setting up for an important experiment only to discover on the day-of that your lab has run out of a critical reagent. This setback can be amplified if you have missed an important data point or have to remake reagents, set up new cell cultures or rebook time on shared equipment e.
While running out of reagents happens to the best of us, there are steps you can take to minimise this risk while also avoiding unnecessary duplicate orders. Here are some tips to organize your stockroom and fridges: Designate specific, clearly-labeled storage locations for each reagent or category of reagents to ensure that newly-delivered items can easily be found by all lab members.
Remove expired and obsolete reagents from your storage space.
CHEMISTRY REAGENT MANUAL Prepared by Chemistry Department, SGTB Khalsa College preparing the chemistry reagents in a laboratory, correct proportion of chemicals and /or solvents as well as procedure is (name of reagent, date of preparation, hazard warning) as per the instructions.
We bring the highest level of quality and attention to detail to our clients to assure that their analytical method development and validation projects are successfully executed. There are standard organisms used for this test. Testing to show the preservative is effective should include out to and including the beyond use date.
In addition to the standard organisms, it is always good practice but not required to test the effectiveness of the preservative against organisms isolated from the facility in which the product is compounded. DYNALABS can work with the customer to help determine if testing of resident organisms found within the compounding facility is feasible and beneficial to them. The criteria that can directly impact stability are: Compound Formula Container Closure System Handling and Storage Conditions Once a claim has been validated, any significant changes in these criteria may require some level of revalidation.
This may not mean all the original validation testing be conducted, however there may need to be some smaller subset of the testing that needs to be repeated. In additions to claims made on end use doses, there may also be claims made on intermediate materials that are maintained within the pharmacy, that are used in the compounding of end use doses. These must also be included in the design of the stability testing program.
However, we prefer to work with the customer to first create families of compounds based on formula, compounding processes, container closure system, and handling and storage conditions. We then apply our considerable experience and knowledge to design a testing program that minimizes the costs of implementing a stability program, while maximizing the value gleaned from the data created. Uniformity may be demonstrated using two methods, content uniformity or weight variation.
The number of samples is established during the experimental design phase of the project.

GMP Quality Documentation – Control, Tracking and Distribution In this SOP you will find mainly the role of document control officer during the initiation, creation, circulation and approval of new quality related documents. It also describes the procedure of modification and review of existing document using a documentation database. Management of existing and superseded documents is also a part of this procedure.
You will see all the forms referred during the instruction are attached at the end of the procedure. Preparation, Maintenance and Change Control of Master Documents This SOP particularly focused on the management of master file documents like specifications, control methods, raw materials, finished goods and packaging specification and test reports, formulation, stability files etc required to generate during the product registration in the market.
Nov 12, · Re: Reagent expiration? The R will get “chunky” and leave black marks over time if exposed to moisture. This is the reason why we have two cylinders in the TF one for CL testing only as the powder will stain the cylinders.
With FDA exerting increasing influence over certain areas in healthcare laboratories, such as Transfusion Medicine, GLP will also increase in importance in clinical laboratory medicine. I am struck by the parallels between the two sets of regulations and their histories. Lessons from history There are two lessons I’ve learned from the study of history. First, history repeats itself and second, those who do not learn from history are doomed to repeat it.
The food and drug industry, because of mistakes, required federal regulations to ensure safe consumer products. Our industry, because of such incidents as Pap smear mills producing erroneous results, needed strict federal intervention to ensure quality and accurate patient specimen results. I would like to review the GLP story. Both regulations driven by harm to the public Like CLIA, GLP has its roots in a history of mistakes by food producers and drug manufacturers that resulted in harm to the general public.
Because of these mistakes, the federal government, under the auspices of the Food and Drug Administration FDA , stepped in to regulate the food and drug industry.

Our mission is to support manufacturers, packagers, raw material suppliers and formulators with timely and accurate test results in nearly every phase of development from conception to the release of a safe and effective final product. Laboratories has extensive experience providing both method development and validation services. Most often we are asked to develop a method for the analysis of an active drug substance in a finished product.
Reagents which are received without an expiration date are to be assigned an expiration date of one year following receipt. Unless specifically stated in the instructions for preparation, all reagents prepared by the laboratory shall be assigned an expiration date of one year following preparation.
Sherwood, Margaret Fri, 03 Feb Our safety people do a yearly inspection of chemicals etc. Friday, February 03, 8: Yellow granular dust covered the top. I immediately notified our security folks, who called in the local bomb squad. The squad took the bottle out into the field next to the hospital and detonated it. Left a nice little crater

Therefore, the freeze drying process is very important for solid reagent formulations in the commercial immunoassay diagnostic kits. Shelf Life of a Product: The quality of a product changes with time and this change in product quality is affected by storage temperature, humidity, packaging protection and product formulation. Shelf life is different from expiration date. Shelf life refers to quality and expiration date refers to safety. A product that has passed its shelf life might still be safe, but quality is no longer guaranteed.
to include “ordering and interpreting laboratory tests.” This rule change took effect on March 25, While the definition was broad, most pharmacies nationally focus primarily on CLIA- before signing and dating. Adhering to the expiration date of the test system and reagents, as applicable; Performing quality control, as.
Closed but untaped mL bottles have a shelf life of 4 years. Closed but untaped mL bottles have a shelf life of 21 months. Transpiration loss occurs mainly around the cap circumference and not through the container walls. There is no difference between the transpiration loss of water versus hydrochloric or nitric acid aqueous solutions. The shelf life can be accurately predicted from the ratio of the cap circumference to the surface area of the solution exposed just below the head space.
Transpiration loss is linear with time. Typically, Inorganic Ventures stock items have an average shelf life of years.
