  1. Thanks for letting us know, I worked with Imelda on a couple of projects when she was at Liverpool BTS. I always enjoyed her humour and approach to life. Noel

    I. Position Description Manufacturing Technologist II personnel participate in all activities related to the manufacturing of Hemo bioscience products as well as process evaluation. This position is responsible for following standard operating procedures, best laboratory practices, current good manufacturing practices (cGMP) and current good documentation practices (cGDP) to ensure products are manufactured and systems are maintained to meet internal and customer specifications. II. Major Areas of Responsibility Manufacturing Laboratory, technical and analytical III. Specific Responsibilities of the Job Include the following. Other duties may be assigned, as needed. Adheres to manufacturing schedule to ensure products are prepared and released to inventory to meet shipping deadlines. Follows SOPs, best laboratory practices, current good manufacturing practices and current good documentation practices to ensure products are manufactured to meet specifications. Participates in all technical and non-technical aspects of the manufacturing process from receipt of raw material to release of finished product. Activities include, but are not limited to: Customer label approval Product label generation and printing Product filling and capping Lab inventory and cleaning Temperature monitoring of refrigerated systems Equipment maintenance Specimen processing Solutions preparation Raw material qualification Equipment IQ/OQ/PQ Product Manufacturing Product Testing (In-Process & Bulk QC) DHR Creation & Maintenance Maintenance of updates to manufacturing SOPs through document control processes o Process Deviation Write-ups Responsible for documentation of all manufacturing related activities Provides suggestions for better production and staff performance
  2. Hemo bioscience has developed a new polyagglutinability kit and is in the stages of validation and testing. Previously we had access to Tn polyagglutinable cells. However we lost access to the donor who had acquired Tn polyagglutinability. Does anyone have access to a patient or donor that is exhibiting Polyagglutinability? We manufacture Neuraminidase treated cells here so we have the general T polyagglutinability covered. Thanks in advance. Noel Brown President Hemobioscience Inc.
  3. Sad news indeed, thanks for letting us know. Noel
  4. If you subscribe to a whole Blood Proficiency test ( like CAP JAT) the samples contain reverse group antibodies anti A, Anti B etc. and a couple of antibodies. its easy to write your own study looking for carryover in the adjacent samples. Alternatively Hemo bioscience makes and sells a validation kit for instrumentation and this contains similar materials....
  5. Thanks for letting us know, I worked with David a long time ago on an IgG quantitation assay.
  6. Here is an example of how to calculate numbers of units to be screened from a Proficiency test we designed a couple of years ago. It makes a nice worked example. Frequencies and Donor Screening The frequency of the c (small) antigen is 80% in Caucasians, 96% in Blacks, and 47% in Asians (Refer to Table 3 for additional information regarding Rh antigen frequencies in various populations).3 Antigen Symbol Caucasian Black Asian D 85% 92% 99% C 68% 27% 93% E 29% 22% 39% c 80% 96% 47% e 98% 98% 96% Table 3: Common Rh blood group antigen frequencies3 The frequency of the K antigen in 9% in Caucasians and 2% in Blacks. The K antigen can be found at higher frequencies in specific populations—found in approximately 12% of Iranian Jews and can be found in up to 25% of the Arab population (Refer to Table 4 for additional information regarding the antigen frequencies associated with the Kell blood group system). Antigen Symbol Caucasian Black Other K 9% 2% Iranian Jews = 12% Arabs = As high as 25% k (small) 99.8% 100% Kpa 2% Less than 0.01% Kpb 100% 100% Jsa 0.01% 20% Jsb 100% 99% Table 4: Common Kell blood group antigen frequencies3 Problem #1: How many units of pRBCs should be crossmatched in order to find 3 antigen negative units? 1. Given that ~80% of the population will have the c (small) antigen, ~20% of the donors should be negative for the c (small) antigen. Additionally, given that ~9% of the population will have the K antigen, ~91% of donors should be negative for the K antigen. **NOTE: When multiple antigen frequencies are involved, you must multiply the antigen negative frequencies together. In this case we would multiple 20% and 91% to account for the donors who are c (small) negative and K negative. 2. Number of units to be crossmatched = x x = 3 units/0.18 = 16.7 (or 17 units) 3. The blood bank should crossmatch 17 units, where 3 of the 17 units should be compatible.
  7. There is no licensed anti COb in the USA, i have a few vials of raw plasma in a freezer that i use for research purposes...
  8. I suggest you try any high potency IgM anti D which these days is a monoclonal and thus not high protein. The anti D on your bench right now ( immediate spin) should work.
  9. Add some Dextran to a plasma sample, it should do the trick and will save you a lot of time and effort freezing and retaining samples etc.

  11. So.. just a quick word of warning, its easy to grind up seeds and do an extraction. But what i have found is that the extraction may or may not work and its a bit fickle. if you go down the path of making your own lectin you must QC it by using either polyagglutinable cells or at the very least prepare Neuraminidase treated cells. If you don't you could end up with false negatives.
  12. We have one in development at the moment. Our previous supplies of Arachis and Glycine proved to be unreliable.
  13. yes I trained at Manchester NBS under Peter Howell and did my Fellowship there. Now living and working in the USA as President of Hemo bioscience Inc.
  14. I haven't heard it called Flying squad blood for Donkeys years, srichar3 are you from the UK?
