While the IGBB Service Center can perform low-risk, fairly routine biomolecular tasks on a fee-per-service basis, some of your research goals may require (or would most readily be completed with) the help of professionals trained in advanced procedures and/or data analysis techniques. The IGBB research associates, most of whom have Ph.D. degrees and/or many years of practical experience, can be hired to conduct research tasks associated with their specialties. For example, let's say you need an expert in RNA isolation and RNAseq to help you complete a portion of a research project. You could train a student or postdoc to become proficient in these research tasks, but you may not have the experience, time, or money to train someone. Moreover, you may not have the instrumentation you need to do the research correctly. This is where the IGBB can help. Rather than training someone new, you can hire a highly skilled IGBB scientist to perform the research for you. The savings in cost and time is tremendous! The process works like this:
- The principal investigator (PIs) interested in determining whether
the IGBB can help them in their research/analyses contacts one of the IGBB's Research Leads.
- The Research Lead(s) sets up a meeting with the PI to discuss project goals, feasibility, and
approaches. This consultation is free.
- If the PI and the Research Lead agree to a research plan, the
Research Lead
will generate an itemized quote for the PI that includes salary, fringe, reagent
costs, machine costs, etc. The duration of the employment agreement depends upon the needs of the customer and can range from a few hours to several months. In addition, IGBB employment agreements can cover fairly low weekly time committments spread out over long stretches (e.g., a customer may hire an IGBB employee to work on a project 5 hours a week for four years). Overhead charges and/or HPC² retainage costs may or may not be
applicable. Once a plan is set between a PI and an IGBB Research Lead, a final quote will be sent to the PI for approval. Once the PI approves the quote, work can begin.
If you don't have funding in hand, but are working on a grant proposal, you can include the participation of an IGBB expert-for-hire in your proposal budget (note: you must make such agreements with the expert-for-hire through a MyIGBB itemized quote). To discuss a hiring an IGBB expert, please contact one of the IGBB's Research Leads by phone or e-mail.
NOTE: PIs are asked to consider whether the participation of an IGBB employee in a project merits that employee's inclusion as a co-author on a resulting manuscript(s). The decision ultimately lies with the PI. However, the IGBB encourages IGBB staff and faculty involved in
Proposal Partnerships and
Experts for Hire to discuss/negotiate co-authorship with PIs before starting work on a project.

In vitro embryo production (IVP) procedures frequently include supplements such as serum and/or co-culture with various types of somatic cells. However, the presence of undefined serum in culture media introduces a variation from batch to batch, increases viral or prion contamination risk, and leads to problems during fetal development. The aim of the present study was to investigate the possibility of using chemically defined-synthetic serum substitute (SSS) in place of fetal calf serum (FCS) during maturation and long-term culture to stimulate in vitro maturation (IVM), fertilization (IVF) and subsequent embryo development. In Experiment I, the effect of the protein source on in vitro maturation was tested by maturing oocytes in culture media supplemented with 10% FCS (Control Group), 10% SSS (Group I) and 10% SSS+10 ng/ml epidermal growth factor (EGF) (Group II). In Experiment II, effects of SSS on both oocyte maturation and embryo development during in vitro culture (IVC) were tested by maturing oocytes in media supplemented with 10% FCS (FCS Group) or 10% SSS+10 ng/ml EGF (SSS Group), followed by IVF and IVC in SOF media supplemented with 10% FCS and 10% SSS on day 4 for FCS and SSS Groups, respectively. Even though rates for cleavage and development to blastocyst stage were not different, blastocyst cell numbers were higher in Group II containing SSS and EGF. The SSS supplementation group had higher apoptotic nuclei as compared to the FCS Group in Experiment II. Transcripts for heat shock protein 70 (Hsp70), interferon tau (IF-tau), DNA methyltransferase 3a (Dnmt3a), desmosomal glycoprotein desmocollin III (DcIII) and insulin-like growth factor II receptor (Igf-2r) were altered in different culture conditions in Experiment I. However, only glucose transporter-1 (Glut-1) mRNA was different in the SSS and FCS Groups in the second experiment. In summary, SSS and EGF in maturation medium and replacement of FCS with SSS alone in culture medium on day 4 of IVC support oocyte maturation and embryo development in vitro. However, significance of culture condition induced changes on the genome-wide abundance of messenger ribonucleic acid and the significance of the apoptotic nuclei during fetal development still remain to be determined.
